I am wondering if TDDFT in NWChem can work with background point charges?
Looking for the tips! Thanks!

Hi, Yes. This can be done.

Just add a bq block to your input

bq
load bq_charges
end

where bq_charges is a file with the following format: Bq, x, y, z, charge

Bq 6.216300 3.061700 7.435000 -0.33333333
Bq 5.106200 4.171800 6.715200 -0.33333333
...

Also set the following options for the geometry block

geometry units angstrom noautoz nocenter noautosym
...
end

Best,

thanks very much!
One more question: At the moment is the TDDFT frequency calculation numerical or analytical?
