Dear Netters,
I have calculated neutral radical molecule using:
#P UHF EPR-II TD(NStates=5,Root=5) Density=all IOp(6/12=3) Prop=EPR
I would like to compare two algorithms in G98: CI one-particle VS CI density.
My question is:
Where I can find formulae and algorithms installed in Gaussian 98, Revision A.7
calculating:
B1) total atomic charges and B2) total atomic spin densities by the:
Population analysis using the CI ONE-PARTICLE DENSITY.
B1) total atomic charges and B2) total atomic spin densities by the:
Population analysis using the CI DENSITY ????
My second question is: why G98 A.7 alarms when calculating:
Electrostatic Properties Using The CI Density
Warning! Using spin rather than total density!
--- Only the electronic contributions will be computed
What it is new in these algorithms: CI one-particle density VS CI density
installed in G03?
Merry Christmas and very Happy New Year for You!
