Abstract

The use of photoacoustics as a method to obtain enthalpy and volume changes of photochemical reactions was discussed. It is useful for photobiological or other reactions in water where the thermal and inherent volume changes can be separated by measurement at the temperature of maximum density. The apparatus used is suitable for the study of proton pumping in bacteriorhodopsin and oxygen formation in photosynthesis.
