Optoacoustic and Optogalvanic Spectroscopy
The optoacoustic effect (generation of sound by absorbed radiation) and the optogalvanic effect (change in impedance of a gas discharge due to absorbed radiation) are becoming increasingly widely used in spectroscopy. Both are very sensitive and have been used in diverse applications. Several examples of the use of techniques based on these effects are described.
