The exchange of the NH proton in 1,2,3, benzotriazole has been studied by total line shape analysis of 1H NMR spectra. The rates of this process have been found to be dependant on concentration, temperature and the presence of water. The activation parameters (Ea, D*H, D*S, D*G298) for this rate process have been determined.
