摘要：

Electron nuclear double resonance (ENDOR) spectra have been observed for biphenyl and a number of mono- and dimethyl substituted biphenyl free radicals in solution. The hyperfine structure coupling constants have been determined with an accuracy of +/- 10 kHz. Due to the inherent higher resolution and simplicity of the ENDOR spectra, new results have been obtained. which in some cases deviate from former ESR data. The experimental electron spin densities are compared to those resulting from a Huckel molecular orbital calculation, using an inductive model for the methyl group substitution effect. Comparison has also been made to calculations using McLachlan's method.
