Abstract

The photoacoustic process has great potential as a spectroscopic technique appropriate for opaque, highly scattering or weakly absorbing samples, all unsuitable for use with standard absorption spectroscopy. In particular, it is suited to liquids with low optical absorptions, for example the sensing of hydrocarbon pollutants in water [1].
