“…An estimation of this activation energy can also be obtained by comparison with substituted diazenyl radicals. Decomposition rates of N2CH 3 have been estimated at 3 x 106 s -I [iS0] and 9 x 107 s -I[152] at room temperature and an activation energy of 14 kcal mol -I was calculated for the dissociation of N2C2H S[153].
