摘　　要：By using photoacoustic calorimetry, a photoacoustic measurement system is applied to determine the Co-C bond dissociation energy of n C4H9Co(Salen)H2O, which is 116±8kJ·mol-1. This value is in agreement with the activation enthalpy of the Co-C bond homolytic cleavage reaction that obtained by the kinetic method.By using photoacoustic calorimetry, a photoacoustic measurement system is applied to determine the Co-C bond dissociation energy of n C4H9Co(Salen)H2O, which is 116±8kJ·mol-1.
