Hi,

     I am performing a Hartree-Fock calculation on the diatomic molecule, MgCl+ ion using Gaussian 03.  I am interested in the optimized wavefunction of the singlet state.  Is there an output option in Gaussian to output the complete antisymmetric wavefunction of the 7 valence electrons?

Thanks,
Huzeifa

Daniel,

Yuck! A very ugly error in the first edition of the book.

This error is corrected in the second edition (the same phrase appears=20=

now on p. 195 with the word "negative" preceding "orbital energy"). I=20
must have made the correction on the proofs because I failed to include=20=

it in the errata that are listed on the web. Sorry... I'll update the=20
erratum for those who have the first edition.

The errata are listed for first AND second editions (just a few so far=20=

for the second edition, thankfully...) as links on the page: =20
http://pollux.chem.umn.edu/~cramer/backcover.html

Best regards,

Chris

Daniel,


Yuck! A very ugly error in the first edition of the book.


This error is corrected in the second edition (the same phrase appears
now on p. 195 with the word "negative" preceding "orbital energy"). I
must have made the correction on the proofs because I failed to
include it in the errata that are listed on the web. Sorry... I'll
update the erratum for those who have the first edition.


The errata are listed for first AND second editions (just a few so far
for the second edition, thankfully...) as links on the page:=20

Dear CCLers
I'm trying to perform an ab-initio calculation with Gaussian03 
(mp2=full/6-31+g(d,p) geom=connectivity) on molecule of 197 atoms.
I have never performed such a calculation before.
I don't know how to set % mem to an appropiate value for my calculation.
Can anyone help me?

Thanks in advance
Regards

Lucilla

Dear everybody

I'm performing a charge screening (Mulliken, CHELPG,...) and I'd like to have the charge value for AIM theory. Does 
anybody know how to calculate  net charge for an atom using AIM analysis?

Thanks a lot

Dear Dr. Glossman-Mitnik,
                         Many thanks for your mail. In the conceptual
density functional theory the Koopmans' theorem is generally written as:

        IP = -E(HOMO)  and  EA = -E(LUMO)

and hopefully there is nothing wrong in it.
Some related references are given below:

Molecules" Oxford University Press: Oxford, 1989, p 166.

Hi,

     I am doing a QCISD open shell calculation on triplet MgF+.  I am using Gaussian 03.  Is there a way to output the coefficients of the excited Slater determinants?

Thanks,
Bryan
