Abstract
The ultraviolet absorption spectra of n‐heptene‐3 and tetramethylethylene were measured in liquid and hexane solution phase, between 4000A and 2100A and in vapor phase between 2300A and 1500A. Curves showing the logarithm of the molecular extinction coefficient as a function of the wave number are given for the measurements in the quartz region and tables giving the regions of absorption together with the wave‐lengths of the centers of bands for the measurements with the fluorite vacuum spectrograph. Comparison with earlier work shows the progressive shift toward the visible of the absorption bands in the Schumann region as the hydrogen atoms of ethylene are replaced by alkyl groups, and the parallelism between the spectra of different hydrocarbons having the same configuration with respect to the double bond.Keywords
