ResumoThe sensitivity of a new spectroscopic technique, photoacoustic Raman spectroscopy (PARS), has been improved substantially by the use of high-peak-power pulsed lasers. The theory for generation of photoacoustic signals from stimulated Raman scattering is outlined, and vibration-rotation Raman spectra for CO2 and CH4 are presented. Applications of PARS are discussed, and a comparison is made with other Raman techniques.
