Abstract

Photoacoustic spectroscopy is based on the detection of heat produced following the absorption of modulated monochromatic light by a sample. By changing the probe beam wavelength, we have obtained an action spectrum similar to what can be observed by absorption spectroscopy. Photoacoustic spectroscopy can advantageously be applied to samples, like unicellular algae, the optical properties of which are such that they can hardly be studied by conventional spectroscopic techniques.
