Time-resolved photoacoustic calorimetry: probing the energetics and dynamics of fast chemical and biochemical reactions

Department of Chemistry and Biochemistry, University of Colorado, Boulder 80309-0215.

Time-resolved photoacoustic calorimetry is a new experimental technique that measures the dynamics of enthalpy changes on the time scale of nanoseconds to microseconds for reactions initiated by absorption of light. When the reaction is carried out in water, it is also possible to obtain the dynamics of the corresponding volume changes. This method has been applied to a variety of biochemical, organic, and organometallic reactions.
