| Abstract: | Vibrational spectra are given for ethyl benzoate (EB) as liquid, gas and amorphous solid. Assignation is made for the vibrational spectra of the three phases of EB, with the help of data for crystalline EB given in the literature and the crystalline equimolar ethyl benzoate—titanium tetrachloride complex, and assisted with force field calculations.All fundamental vibrations in EB between 100 and 1800 cm−1 are found. The observed frequencies fit a valence force field, developed for five isotopic congeners of EB, with an average deviation of less than 5 cm−1. |
