Abstract
The development of a photoacoustic calorimeter with a time resolution of 10 ns is presented, and the dynamics of the enthalpy and volume cha nges found in the photodissociation of CO from horse carboxymyoglobin are examined. With this enhanced time resolution a new transient speci es, the lifetime of which is 29 ns at 20-degrees-C, is observed in the ligand dissociation process.
