| Abstract: | In this paper, the theory of pulsed photothermal deflection spectroscopy that accounts for both the propagaton of excitation beam and the finite size of the probe beam is presented and compared with the existed theoretical models. The applicabilities of all theoreticaltreatments are discussed. The beam geometry of pulsed photothermal deflection spectroscopywith tightly focused laser beam excitation is optimized. |
