Abstract The two-photon excitation spectra of gas phase pyrazine-h4 and -d 4 in the region of the S1←S0 transition are presented. The two-photon absorption which is electronically forbidden is induced by-various vibrations of ungerade parity. Because of the different selection rules for two-photon transitions hitherto unknown vibrational frequencies in the excited state 1B3u have been determined.
