THE IONIZATION POTENTIAL AND HEAT OF FORMATION OF THE (CH3)2N RADICAL BY MASS SPECTROMETRY,

Abstract

The ionization potential of the (CH3)2N radical, obtained by pyrolysis of 1.1.dimethylhydrazine and of dimethylnitrosamine, was determined directly as 9.42 plus or minus 0.1 eV. The heat of formation of ((CH3)2N) was calculated to be 30.3 plus or minus 2 kcal/mole. This figure agrees with the kinetic value thus resolving the discrepancy between the latter and previous electron impact values. Electron affinities were obtained as follows: EA(NH2) = 1.05 plus or minus 0.1 eV and EA(NO) = 0.8 plus or minus 0.1 eV. (Author)
