杂环化合物的标准生成焓和共振能

THE STANDARD ENTHALPIES OF FORMATION AND THE RESONANCE ENERGIES OF THE HETEROCYCLIC COMPOUNDS

首先由气相原子生成焓和键焓，计算了９个杂环化合物的气相标准生成焓，与实验结果相符合．并用ＨＭＯ方法计算了这些化合物的共振能．文中还讨论了共振能、键焓对标准异构化焓的影响．

The standared molar enthalpies of formation of some keterocyclic compounds were obtained from the formation enthalpies of the gaseous atoms and the bond en thalpies. The resonance enthalpies(R_E) of the compounds were calculated by HMO method. The effect of the resonance energies and bond enthalpies on the standard enthalpies of isomerization was discussed.
