The dissociation enthalpies of terminal (N-O) bonds in organic compounds

Abstract

Dissociation enthalpies of terminal (N-O) bonds, DH° (N-O), in amine N-oxides, nitrile N-oxides, pyridine N-oxides, quinoxaline 1,4-dioxides, furoxans, nitrones, azoxyderivatives, azo-N, N-dioxides, nitro compounds, nitramines, and alkyl nitrates are calculated from published enthalpy of formation, enthalpy of sublimation, and enthalpy of vaporization data. For each class of organic compounds, the calculated DH°(N-O) values are critically evaluated. The derived DH°(N-O) values can be used to estimate enthalpies of formation of other molecules in each of these classes of organic compounds. © 2005 American Institute of Physics.
