Abstract
The equation ε/ε0 = cos2(θ1 − θ2) recently proposed by Braude and co-workers is developed to account more rigorously for the spectra of unsymmetrical molecules. The results obtained from the revised equation, [Formula: see text] support the interference value of hydrogen obtained independently from spectral data, and suggest a re-examination of the reported theories accounting for the spectra of alicyclic enones and dienones, and for steric effects of type I.Keywords
