Hello,
is there any way to compute a population analysis using the density matrix and the transition density matrix in ADC(2)? Choosing dens =1 or 2, nsing=2, and calc=ADC(2) give errors. Thanks a lot!

This is my input:
basis=def2-SVP
calc=ADC(2)
nsing=2
mem=32GB
verbosity=3
tprint=0.1
dens=1

geom=xyz
12

and the error message:

Dear Edums,
calculation of first-oder properties at the level of ADC(2) is an ongoing project. Unfortunately, this is not available at this stage.

Best regards,
David

Dear David,
oh, I see, thank you very much. Is there any chance of retrieving the matrix elements of the density matrix for ADC(2) corresponding to the excited states? If yes, do you see any possibility of calculating charges fit to the electrostatic potential for this density?
Thanks,

Edums
