Abstract
The matrix isolation spectra of a group of hydrocarbons and polar substituted hydrocarbons indicate that the narrower infrared lines produced by this technique will be exceedingly useful for the determination of functional groups and structural aspects of the hydrocarbon moiety. With the aid of the matrix isolation spectra various types of both methyl and methylene groups can be differentiated in the CH stretching region and thus group frequencies for hydrocarbon components can be determined. Thus, for example, various types of methylene vibrations can be identified and are seemingly strongly influenced by the nature of neighboring groups.
