Popis:	Energy-resolved electron impact was used to measure the appearance energy of CH 2 NH + from azetidine and propargylamine and the adiabatic ionization energy of CH 2 NH formed in the pyrolysis of azetidine. The heats of formation of CH 2 NH and CH 2 NH + 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 Af H 298 0 (CH2NH) of 21 ± 4 kcal tool −1 .
