Abstract

Photoacoustic and photothermal techniques have found wide application in infra-red spectroscopy over the last few years. Samples are illuminated with amplitude modulated radiation which produces excited spectroscopic states. These excited states relax by radiationless de-excitation pathways producing a modulated heat source within the sample. The modulated thermal signal can be recovered by a variety of photoacoustic and photothermal probes. Since the intensity of the thermal signal is a function of the amount of energy absorbed by the sample, the use of tunable radiation sources allows spectroscopy to be carried out. In addition, information can be obtained about the excited state behaviour of the system, and its physical characteristics. Techniques are applicable to a wide range of sample states and types. This paper reviews recent literature in the area, concentrating on the main current trends.
