The temperature dependence of an IR absorption band of CH{sub 3}CN-HCl is characterized by FTIR photometry. The heat of dimer formation at 41{degree}C obtained from this data, {Delta}H{sub D} = {minus}13.8 {plus minus} 1.2 kJ/mol, is used to calculate the equilibrium hydrogen bond dissociation energy, D{sub e} = 21.8 {plus minus} 1.7 kJ/mol. These results are compared with recent ab initio theoretical calculations and empirical estimates based on centrifugal distortion parameters.
