Far infrared spectrum of CD3OH methanol from 40–220 CM−1
- 26 Downloads
The Fourier transform far-infrared (FTFIR) spectrum of CD3OH has been obtained from 40–220 cm−1 at a resolution of 0.002 cm−1, and partially analyzed. Numerousb-type branches have been assigned in the spectrum, ranging over torsional states fromn=0 to 3. The branches have been fitted toJ(J+1) power-series energy expansions in order to obtainJ-independent branch origins. These in turn have been fitted to the torsion-rotation Hamiltonian, and improved molecular constants have been obtained for the ground vibrational state.
