The one and two-photon spectra of the lowest electronic states of pyrimidine are analyzed by means of response theory calculations. Particular attention is paid to the lower onsphoton forbidden (nrt') 'A2 andonaphoton allowed (r&) 'Bi and 'B2 states. Despite being electronically allowed it is found
A CNDO/S Cl calculation of the two-photon vibronic activity of some btu and bzu vibrational modes of pyrenc is prcsented. The two-photon amplitude tensor is discussed in terms of vibronic coupling cocfticients calculated by means of the orbitat-following method. The results are in good agreement wit
