摘要：

Energy-resolved electron impact was used to measure the appearance energy of CH2NH+. from azetidine and propargylamine and the adiabatic ionization energy of CH2NH formed in the pyrolysis of azetidine, The heats of formation of CH2NH and CH2NH+. were determined to be 22+/-3 and 250+/-2 kcal mol-1, respectively, although the presence of a competitive shift makes the results upper limits. A review of past thermochemical determinations leads to a selected value for DELTA(f)H-298(0)(CH2NH) of 21+/-4 kcal mol-1.
