Enthalpy changes that occur during the photocycle of Halobacterium halobium purple membrane fragments have been measured on a millisecond time scale, using photoacoustic detection to obtain modulation photocalorimetric data. Details are given on the ways to obtain quantitative thermodynamic and kinetic information by this method.
