Electron Diffraction Study of the Toluene Molecular Geometry

Abstract

On the basis of an electron diffraction analysis, the following structural information was obtained on vapour phase toluene molecules: rg(C C) mean 1.399 ± 0.002 Å, r g (C-C) 1.511 ± 0.008 Å, the mean length of the C-H bonds is 1.117 ± 0.005 Å (r g ). The methyl C-H bonds are at least 0.020 Å longer than the phenyl C-H bonds which are not longer than those in benzene
