Hello CCLers!


I am wondering about the possibility of utilizing AFM/ STM technology to
investigate how possible cold flow improver additives adsorb on the surface
of n-alkane waxes.  (Polymeric Cold Flow improver additives adsorb on to
the fast growing faces of developing wax crystals, retarding the growth and
give rise to smaller crystals rather than large flat plates, which can
interlock and block fuel flow in filters)  I am aware about the simulations
performed by Bill Goddard's at Caltech
(http://www.wag.caltech.edu/msc99/talks/e3/index.html) but I would like
some references on experiments.  Any references, suggestions, comments will
be appreciated. ( I am somewhat skeptical about the simulation results.)

Best Regards,

 Alo,
     I've been doing some calculations in atomic Fe
 using G98, and I have found that the result in some
 cases depends on the starting orbitals: is this
 a failure of the program?
     For example, if in a Hartree Fock
 calculation I use the keyword GUESS=READ to
 read the orbitals previously
 generated by B3LYP, the computation converge
 to a different energy that if had not used
 starting orbitals at all.

    I attach two files (singlet state of Fe0).
 When I run hfock2.com using orbitals generated for
 the same system with B3LYP, the result is different
 from hfock1.log .
 Maybe I am not using properly the restart file?
 Any hint about what is happening will be much appreciated.

         Sponsored by: CAChe Group, Fujitsu

Monday,  Nov. 13, 1:30 - 2:30 PM - Room #305, Marriott Downtown
Tuesday, Nov. 14, 3:00 - 4:00 PM - Room #307, Marriott Downtown
                     333 Figueroa Street, Los Angeles, CA

Modeling of reaction pathways, transition states, prediction of kinetic and
thermodynamic data will be illustrated from several published papers that
utilize CAChe, an easy-to-use computer aided chemistry package that runs
on Windows and Macintosh. Minimizing unwanted side reactions, optimizing 
yields, suggesting reaction conditions, and determining product composition 
will also be discussed. Prediction of  physical, chemical and biological 
properties such as solubilities, spectra, reaction rates, carcinogenicity, 
etc. will also be covered.

Subject: sp^2 hybridization


When we teach hybridization at an elementary level we say that sp^2
hybridization involves the mixing of three pure atomic orbitals, s, py and
pz.

However the formal expressions for the linear combinations of orbitals show
an asymmetry in that one of the hybrid orbitals consists of contributions
from s and Py only while the other two hybrid orbitals are genuine mixtures
of all three pure A.O.

My question is whether it is possible to define the hybrid orbitals so that
all three are guninely mixtures of the three pure A.O. and if so why is
this not generally carried out?

eric scerri

hello:
	I think the answer may be that sp^2 hybrids are mixtures of
Y(l=0,ml=0), Y(l=1,ml=-1), and Y(l=1,ml=+1). If this is taken as a
definition, then you can say that the 3 hybrids are mixtures of the 
3 AO's.

A LOT of thanks to Valentine, Per-Ola and Guilherme
Ths solution to change the calculation parameters is to put everything
on the same line at the end of the coordinates, along with the READ
option for SCRF, and gaussian understands (Never trust the manual...)
Good luck to all for you research
