                                  -----
 In recent months there has been considerable interest in the development of a
 common format for the electronic exchange of quantum chemistry data. The
 communications about exchange formats included details of the Crystallographic
 Information File (CIF) which has been adopted by the International Union of
 Crystallography (IUCr) for data exchange and publication submission, and the
 recently published STAR File (Hall, JCICS, 31, 326-333) on which the CIF is
 based. The requests for reprints and CIF/STAR software have prompted us to
 prepare some examples of quantum chemistry data stored in STAR format, and to
 also construct a sample data dictionary similar to that used for the CIF.
 We present this material for discussion and comment. It is not intended to be
 a specific proposal that quantum chemistry data always be exchanged in this
 format, though, in the absence a superior approach, this may be worth
 considering. Certainly there are advantages to using an exchange format that is
 compatible with that of our crystallographic colleagues, as there are areas of
 definite overlap. Readers are reminded that information about the CIF Core
 dictionary 'cifdic.C91', the CIF access tool QUASAR and CIF validator tool
 CYCLOPS are available by mailing 'sendcif &$at$& crystal.uwa.oz.au' and
 including
 the commands 'inquire' and 'help'.
 Attached are a series of sample files. They are presented without discussion
 of the STAR File syntax. Most readers will find that file structures are
 sufficiently self-descriptive to make this unnecessary. Reprints of both the
 CIF and STAR papers are available from any of the above if the reader wants
 to obtain a more precise description of the syntax rules.
 The attached files are:
 (1) An example of basis set functions from the "Handbook of Gaussian Basis
     Sets" by Poirier, Kari and Csizmadia (1985) in STAR File format. This
     data file, and that in (2) and (3), contain the same basis sets. In this
     example the data is expressed in its simplest and most verbose format in
     which each basis set is stored in a separate data block. It is not sugg-
     ested that this, or those in (2) and (3), are the preferred method of
     storing basis sets; they are shown simply to illustrate the diversity of
     formats that the STAR syntax provides. The multiple data blocks (i.e.
     blocks of data preceded by 'data_*') used in this example provide enormous
     flexibility for the individual definition of basis sets, but are less
     efficient in terms of storage volume over (2) and (3) below.
 (2) This is the identical data to (1) but the basis sets are placed in data
     blocks for each atom type. The different basis sets for an atom type are
     looped within within these data blocks. This data structure is less
     flexible than (1) but more so than (3).
 (3) Again, this is identical data to (1) but now all the gaussian basis sets
     have been placed in a single data block. Basis sets are in nested loops
     according to atom type and to function type. This data structure is the
     most efficient in terms of storage volume but least in terms of data
     flexibility [the addition of a new data item to any basis set (e.g. the
     oxidation number) would require a change to all basis sets].
 (4) The example files (1), (2) and (3) contain codes for source references and
     comments for the basis sets. This file contains the references and comments
     in STAR Format. The codes used here match those used in (1), (2) and (3).
     Note that the STAR construction would have permitted the full reference
     text and the comments to be included with the primary data [i.e. in files
     (1), (2) or (3)] but this would significantly increase the volume of these
     files.
 (5) This file is a sample 'data name' dictionary which defines the data items
     used in examples (1) to (4). Note that the format of the dictionary is also
     a STAR file, with its own set of specialized data names (these are defined
     at end of the file). The dictionary file serves a number of very important
     purposes. It defines each data item so that it may be used for global data
     exchange (there must be no ambiguity about the nature of the data used in
     an exchange file) and it specifies the attributes of the data (e.g. data
     type, numerical contraints, units, etc.). The latter is particularly useful
     for the computer validation of data names and attributes. The program
     CYCLOPS was used to validate the above files and the dictionary itself!
 (6) This file contains data from an SCF run for the water molecule using the
     program CADPAC. It is given here to illustrate how a wider diversity of
     quantum chemistry data is stored in a STAR File. Note how the data names
     are constructed in a hierarchical order according to their function. This
     assists in their grouping in the file and in the dictionary. If the STAR
     syntax was adopted for global data exchange by quantum chemists, data
     names would need to be defined for all commonly used quantities. An
     important spin-off of these definitions is that quantum chemistry would
     then have a common set of 'standard data' items.

 ;   Unpublished results.
 ;
  C11
 ;   This basis set has been checked carefully but the energy does not agree
     with the literature value, the basis appears suspicious and there is most
     likely an error in the literature (12.12.1, Reference R70).
 ;
  C12
 ;   Modification of basis set from reference R18.
 ;
  C13
 ;   Exponents same as reference R33.
 ;
  C14
 ;   The exponents are those of reference R21 or R29, where the d-orbitals were
     augmented with an extra exponent.  The exponent was optimised using a
     Reffenetti type general contraction scheme for the s and p exponents.
     Here the new set of d's is arbitrarily reported with previously reported
     contraction schemes for the s and p exponents.
 ;
  C15
 ;   The core (the contracted function) was optimised on the two electron ion
     and the other exponents were optimised on the four electron ion fixing
     the core part.
 ;
  C16
 ;   This basis set is a modification of one in reference R29.
 ;

     reference R56.
 ;
  C46
 ;   The atomic expansion coefficients were given but no details of the
     contraction scheme is given.
 ;
  C47
 ;   The core part is a truncated set from reference R37.
 ;
  C48
 ;   Contraction scheme given but no contraction coefficients are reported.
 ;
  C49
 ;   Originally from S. HUZINAGA, "Approximate Atomic Functions I",
 Department
     of Chemistry, University of Alberta, Edmonton, Alberta, Canada, 1971.
 ;
  C50
 ;   The 21G valence was obtained from the 6-21G basis set and the core
     representation was optimised keeping the 21G part fixed.
 ;
  C51
 ;   Optimised at the UHF second order Moeller-Plesset perturbation level
     (UMP2).
 ;
  C52
 ;   The p functions were optimisd for the excited P state, fixing the s
     functions.
 ;
  C53
 ;   Optimised on the excited P state (^3^P).
 ;
  C54
 ;   The authors suggest that a split valence basis set can be generated by
     simply splitting the outer valence shell into two parts, one consisting of
     N-1 and the other of one primitive GTO, leaving exponents and contraction
     coefficients as given.
 ;
  C55
 ;   The basis sets were optimised for the 4s^0^3d^N+2^ configuration,
     including copper which was optimised for the d^11^ state although not
     allowed by the Pauli principle.  It was found by the authors that d bases
     for transition metals should be optimised for the d^N+2^ configuration
     rather than for the ground-state configuration.
 ;
  C56
 ;   Possible contraction schemes are discussed in reference R56.  Similar
     contracted sets exist in reference R22.
 ;
  C57
 ;   Uses core functions of the 6-21G basis set of reference R77 and R87, only
     the 31G part is new.
 ;
  C58
 ;   The coefficients for the 6th and 7th s functions (repeated function) were
     determined using the ratio as reported for chlorine in reference R27.
 ;
  C59
 ;   The basis set reported in reference R25, contained a printing error, the S
     coefficient should be 0.19825... not 0.09825...
 ;
  C60
 ;   The energy does not agree with the literature value.  There is a possible
     error in the literature.
 ;
  C61
 ;   These basis sets (exponents and contraction coefficients) were optimised
     for total atomic energies by a procedure to give good valence shell
     orbital energies (prevent collapse to the core).
 ;
  C62
 ;   See PKC Table ATOM.2.1 for a possible contraction scheme.
 ;
  C63
 ;   The energy reported is for the uncontracted basis set.
 ;
  C64
 ;   The original basis set is from T.H. DUNNING, unpublished results.
 ;
  C65
 ;   This basis set is a modification of one in reference R21.
 ;
  C66
 ;   This basis set is one of two similar basis sets.  Both basis sets are found
     to be critical points.
 ;
  C67
 ;   The exponents are originally from S. HUZINAGA (see C49).  The contraction
     coefficients have been optimised to minimise the atomic energy.
 ;
  C68
 ;   Same as C67 but all the p exponents and the last four s exponents were
     optimised on the negative ion.
 ;
  C69
 ;   Same as C67 but extra p functions were added.
 ;
  C70
 ;   The energy is for the ^3^D state.
 ;
  C71
 ;   To preserve the valence shell, the two smallest s exponents and the
     smallest p exponent are taken from the 7s3p basis of reference R2 and the
     remaining exponents are energy optimised.
 ;
  C72
 ;   To preserve the valence shell, the four smallest s exponents and the two
     smallest p exponents are taken from the 10s6p basis of reference R2 and
     the remaining exponents are energy optimised.
 ;
  C73
 ;   The basis set is misprinted in the paper, the contraction scheme for the s
     functions is (6:2:2:1:1) to give a 5s4p2d basis set.
 ;
  C74
 ;   This basis set is a scaled phosphorus 4-31G basis set, using Slater
     exponent ratios.
 ;
  C75
 ;   The coefficients were optimised.
 ;
  C76
 ;   This basis set is a least squares fit to the 12s9p basis set of
     reference R14.
 ;
  C77
 ;   The p exponents are from reference R98 and were optimised on the ^2^P state.
 ;
  C78
 ;   The p exponents are from reference R98 and were optimised on the ^3^P state.
 ;
  C79
 ;   The Si basis set reported in reference R80, contains a printing error.
     The contraction coefficient for the 9th s-function should read 0.694463
     instead of 0.650911 and the 1st p-function coefficient should read
     0.033008 instead of 0.037336.

 #
 # _definition           The description of the item.
 #
 # _enumeration          A permissible value for an item. The value 'unknown'
 #                       signals that the item can have any value.
 #
 # _enumeration_default  The default value for an item if it is not specified
 #                       explicitly. 'unknown' means default is not known.
 #
 # _enumeration_detail   The description of a permissible value for an item.
 #                       Note that that the code '.' normally signals a null
 #                       or 'not applicable' condition.
 #
 # _enumeration_range    The range of values for a numerical item. The
 #                       construction is 'min:max'. If 'max' is omitted then the
 #                       item can have any value greater than or equal to 'min'.

 #                       list. Possible values 'yes','no' or 'both'.
 #
 # _list_identifier      Identifies a data item that MUST appear in the list
 #                       containing the currently defined data item.
 #
 # _name                 The data name of the item defined.
 #
 # _type                 The data type 'numb' or 'char' (latter includes 'text').
 #
 # _units_extension      The data name extension code used to specify the units
 #                       of a numerical item.
 #
 # _units_description    A description of the units.
 #
 # _units_conversion     The method of converting the item into a value based
 #                       on the default units. Each conversion number is
 #                       preceded by an operator code *, /, +, or - which
 #                       indicates how the conversion number is applied.
