Assignment of the FIR and IR absorption spectra of the methanol isotopic species

We are performing a systematic investigation of the infrared and far-infrared absorption spectrumof various isotopic species of methanol by high-resolution Fourier transform spectroscopy.The entire spectra of CH3OH and CD3 OH between 30 and 1250 cm' have been measured inseveral segments on the Bruker Fourier transform spectrometer of the Justus Liebig University ofGiessen. Measurements for the isotopic species CH3180H, 13C113011, 13CD3OH and CH2DOH arein progress on the same spectrometer.
