# Is there any software package for quantum chemistry that includes CAMB3LYP?

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?

• CAM-B3LYP is implemented in Gaussian. Please look again. – pH13 - Yet another Philipp Jan 29 '16 at 15:25
• CAM-B3LYP is also implemented in ORCA (free, but for non-commercial use only). – hBy2Py Jan 29 '16 at 15:34
• It seems I have an old version of the Gaussview program I use to generate my input files. I will just have to write the input file manually instead. – nordmarj Jan 29 '16 at 15:53

CAM-B3LYP is present in Gaussian, Q-Chem, GAMESS, NWChem, ORCA, DALTON, DIRAC, and perhaps other major software packages, either as cam-b3lyp or camb3lyp, however keywords are entered.
• ... and Dalton (example for $1 ~\gamma$, $2 ~ \gamma$, and $3 ~ \gamma$ absorption) and Dirac (example). – Eric Towers Jan 29 '16 at 21:53
