I wanted to recover the damped and regular TPA spectra for LiH as published in https://aip.scitation.org/doi/pdf/10.10 ... ?class=pdf .
The results I got however do not make much sense to me. I attach two outputs. The struggle I have is regarding enormous TPA transition moments
obtained with damped calculations. For instance, for the S1 state and regular TPA I get the averaged TPA transition moment of 2788.8
and the excitation energy is 0.12804 a.u. So I would expect that for one-photon frequencies of ca. 0.06402 a.u. I will have similar
values but these are:
as I get in attached files. I do not understand it completely.
On the other hand, for binol studied in the above paper, I get correct values of TPA cross-section in GM units.
Do I miss anything in my damped TPA results/input?
Find answers or ask questions regarding LSDalton calculations
