Abstract
A pulsed laser photoacoustic technique is described. It is optimized f or the simultaneous investigations of multiphoton absorption processes as well as rotational relaxation and vibration relaxation studies. Th e experimental procedure is presented, concerning the calibration of t he photoacoustic detector/cell set-up, applying the transmission spect roscopy technique. The obtained relationships, which can be alternativ ely used for the sensitivity curve S(p, gamma, T) of the apparatus, ar e analysed. A previously proposed model is confirmed.
