| 摘 要： | A new approach to the hydrogen bond strength distriubtion has been developed based on thehydrogen bond strength distribution model proposed by Coleman et al. By using the method ofequilibrium thermodynamics, a thermodynamic equation for describing the hydrogen bondstrength distribution has been derived for the first time. By means of the equation some IR thermalanalysis results can be explained theoretically. Furthermore, the formulas for calculating theenthalpy and entropy change of the hydrogen bond dissociation have been established.
