What is the Gaussian input format to calculate Franck-Condon Factor including Duschinsky rotation ? Also what is the keyword to print the assignments?

27 March 2019 0 3K Report

I want to calculate FCF between the neutral ground state and cationic ground state, in Gaussian. I want to simulate the vibrational spectra. I used the sample input from Gaussian but it does not print the assignments of the vibrational lines. Using PRTINT=0.5 also doesn't help.

Could someone post a input that can do the job.

Thanks for your help.
