Abstract
The vacuum ultraviolet spectra of the complete series of fluoroethylenes were measured from 2000 to 1150 Å under moderate resolution. The transitions are easily identified in all the spectra. In most cases their maxima are only slightly displaced from their position in ethylene, but a very large hypsochromic shift is found in going from the tri‐ to the tetrasubstituted derivative. Three Rydberg series are observed in all the spectra, converging to the ionization potential. They all exhibit vibrational fine structure dominated by stretching and twisting vibrations. In the highly fluorine substituted ethylenes the first Rydberg band is well separated from the band (at about 1900 Å) as in the highly alkyl substituted derivatives. There is no evidence for transitions of σ electrons in this part of the spectrum except perhaps at the high frequency end of the range (1200 Å).
