Kinetics and thermochemistry of chlorine- and nitrogen-containing oxides and peroxides

摘要: A valence bond additivity scheme based on established thermochemical data is able to reproduce the heats of formation novel species such as O_2ClONO_2, ClOClO_2, ONONO_2, ClOONO, HOONO, FOClO_3, and FONO within ±2 kcal/mol. This finding, together with recently obtained values ΔH_f^o(ClO_3(g)) ΔH_^fo(ClO_4(g)), makes possible a general analysis thermal stabilities known or conceivable chlorine nitrogen oxides potential atmospheric significance. Radical mechanisms for decompositions hexoxide perchloric acid are also discussed.
