I want to do calculations on systems with photoinduced electron transfer, and I've read that the Coloumb Attenuating Method is a modification of the functionals that makes calculations including long-range electron transfer more accurate. Unfortunately I can't seem to find CAM in Gaussian. Is there some other software I should look at?
Not all of QM program use adirect keyword of functional. Some of them you've to mix an ingredient of % functional, says in NWCHem. In that, you aint use keyword 'cam-b3lyp' directly, you need the combination of keywords like
xc xcamb88 1.00 lyp 0.81 vwn_5 0.19 hfexch 1.00
cam 0.33 cam_alpha 0.19 cam_beta 0.46
