Abstract
Evans' method of high pressure oxygen induced singlet–triplet absorption spectra were used to estimate the triplet energies of the title compounds. Phosphorescent emission spectra from EPA glassy matrix at 77 °K were taken for the trifiuorobenzenes. The 0–0 bands of the T ← S absorption indicate that the triplet energy of cis-butene-2 is lower than that of all three trifluorobenzenes.Keywords
