Abstract

The infrared and Raman spectra of solid, liquid and gaseous epifluorohydrin have been recorded. For the fluid phases, there are a number of spectral triplets which can be interpreted as arising from a cis and two nonequivalent gauche conformations. The number of bands which disappear as the solid sample is annealed indicates that a single conformation exists in the crystalline state. The temperature dependence of the intensities of Raman lines for the liquid state is consistent with enthalpy differences of approximately 0.6 and 0.4 kcal mol^−1^ between the most stable and each of the less stable conformers. The existence and identities of the less stable conformers are discussed.
