AO based DFT codes
1) I have the DeFT code but I did not use it yet.
2) From its manual and sample input and output it has many disadvantages.
a) It dose not use the standard basis sets to make a comparison with the
calculations at the SCF and MP2 levels.
b) It dose not print the force fields and calculation of vibrational
frequencies of isotopmers will require a separate job! which is
definitaly a big disadvantage.
c) It dose not allow to use the symmetry explicitly.
3) I think the code from cadpac would be much better. I think the paper of
amos JPC, 1993 97, 4392 ( I hope I got the page number correct) will
explain the advantages an the facilities of the DFT code implemented in
the CADPAC program. We are tring to get the new version of the CADPAC
program for this reason.
