摘要：

The infrared (3500 to 40 cm-1) and Raman spectra (3500 to 50 cm-1) have been recorded for 2, 2, 2-trichloroethyl methyl ether. Additionally, the Raman spectra in the liquid phase have been obtained and quantitative depolarization ratios have been measured. A complete vibration assignment is presented for the trans conformer based on group frequencies and depolarization values. Furthermore, the vibrational assignment is supported a normal-coordinate analysis utilizing a modified valence force field to calculate the normal modes and potential energy distribution for both conformers. From the relative intensities of the infrared line at 606 (trans) and 573 cm-1 (gauche) as a function of temperature the energy enthalpy difference was found to be 161 +/- 11 cm-1 (1922 +/- 134 J/mol) with the trans conformer being more stable.
