实验波长当量与对偶圈——共轭极化与共振效应的统一

Empirical Wavelength Equivalent andSymmetric Coupling Circuit-Unity of Conjugative Polarization and Resonance Effect

本文扩大对偶圈(SCC)模型的应用范围,提出实验波长当量(W)新概念及其计算方法,计算结果表明,苯环的W小于相应的呋喃环的W。从环内共振,环链共振及SCC研究肉桂醛及呋喃丙烯醛的共振效应及W值,结果表明,共轭极化与共振效应是统一的,而且前者和后者是同义的。

Abstract In the present paper the applied range of the model of Symmitric Coupling Circuits (SCO is extended. The new concept of empirical wavelength equivalent (W) and the method for the calculation of the W have been proposed, and the results of the calculations show that the W of benzene ring is smaller than that of furan ring. The resonance effects and the W values of cinnamaldehyde and of furacrolein have been studied from the resonance within ring, the resonance between ring and chain, and the SCC. The results demonstrate that the conjugative polarization and the resonance effect are united, and the former is synonymous with the latter.
