The infrared spectra of a number of methyl substituted polycychc aromatic hydrocarbons have been obtained in the 3000-2700 cm-' region. An apparent correlation is shown to e&t with the spectra in this region and the free valence number for the position of substitution m the parent hydrocarbon.
The possibility of steric effects determining this correlation is considered. introduction FUSON and JOSIEN [l] examined the infrared spectra of the twelve mono methyl-1:2 benzanthracenes and found that the overall appearance of the 3000 cm-l region was similar for methyl groups attached to the low free valence index carbon atoms. The intermediate index isomers, however, were found to show much variety among
