Raman spectrum method for the investigation of hydrocarbons

1. The Raman spectra of seven hydrocarbons of various structures were determined. 2. By a consideration of chemical and spectroscopic data it was confirmed that, in the dehydration of 1,2-dialkylcyclohexanols, o-dialkylcyclohexenes are obtained in which the double bond is predominantly in the position shown in structure (I).
