Abstract The rate constant of the primary decomposition step was determined for four symmetrical and unsymmetrical azo alkanes. From experimental activation energies some literature enthalpy data, following enthalpies formation radicals group contributions were calculated: Δ H ƒ (CH 3 N 2 ) = 51.5 ± 1.8 kcal mol −1 , (C 5 44.8 2.5 (2−C 7 37.9 2.2 [N A ‐(C)] 27.6 3.7 ‐(Ṅ (C)] 61.2 3.1 .
