Abstract
The reaction enthalpy and conformational volume changes can be qualita tively estimated by means of the temperature-dependent pulsed photoaco ustic spectroscopy. The curves for heat-releasing fraction and conform ational volume changes with different temperatures are presented. The simultaneous equations for determination of the enthalpy and volume ch anges are established based on temperature-dependent measurements, and applied to study the photolysis of coenzyme system.
