Abstract

“Observations of the temperature dependence of the nuclear resonance spectrum of the methyl group in Methylammonium chloride solutions have enabled a value for the activation energy. $\Delta $E, associated with the two predominant proton transfer reactions to be desired. A value of $\Delta E=0=1k.$/cals, has been obtained. Rate constants have been measured over a concentration range of 0.25 M to 4.0 M, using similar methods to those previously $applied.^{1}$ Similar experiments are in progress to determine the proton transfer activation energy in ammonium chloride solutions, and will be reported. The results will be discussed with reference to recent theories of proton transfer in amine $solutions.^{2}$”
