 Hi all,
 I am currently working on a project involving the study of two-photon
 absorption (TPA) properties in certain organic materials. I have been tasked
 with calculating the two-photon absorption cross-section for specific
 compounds using Density Functional Theory, and I would like to reach out for
 assistance in this matter. If anyone has prior experience of calculating TPA
 cross section using DALTON code or some other DFT programs, please help. I am
 ready to collaborate with those who are ready to help.
 Regards
 Dr. Renjith Raveendran Pillai
