The C–N bond dissociation energy in nitrosyl cyanide

Abstract

D(NC–NO) has been determined by an electron impact method. The value obtained is 28·8 ± 2·5 kcal mol^–1(120·5 ± 11·5 KJ mol^–1). This value is compared with those obtained for other nitroso-compounds and it is concluded that there is no simple relation between C–N bond dissociation energy and bond length in these compounds, the predominant contribution to the bond dissociation energy being the reorganisation energy in the liberated nitric oxide.
