The Ultraviolet Absorption Spectra of Simple Hydrocarbons II. In Liquid and Solution Phase

Abstract
Molecular extinction coefficients for twelve olefine hydrocarbons have been determined between λ = 3300A and 2100A and are given in the form of curves showing the logarithm of the extinction coefficient as a function of the wave number. The beginning of absorption, as measured by log ε = — 2.0, is quite characteristic of the number of alkyl groups bound to the carbon atoms of the double bond and is only very slightly affected by the nature of the alkyl group.
