| مستخلص: |
Enthalpies of formation (Δ H) of 57 oxygen-containing heterocyclic radicals have been determined from literature values of the dissociation energies of C-H chemical bonds in appropriate molecules. Within the framework of a quantitative structure-property correlation based on the additive-group model, an analysis has been carried out of the obtained Δ H values, the reliability of these data has been shown, and a set of values has been determined of the cyclic stress of the radicals being considered. The parameters of the additive-group method are recommended for the calculation of Δ H for radicals of the considered class. [ABSTRACT FROM AUTHOR] |
