THE SPECTRUM OF CH3OH BETWEEN 200 AND 350 CM-1 - TORSIONAL TRANSITIONS AND EVIDENCE FOR STATE MIXINGS

In the framework of our systematic investigation of the infrared and far infrared spectrum of CH3OH by high-resolution Fourier transform spectroscopy, we present a catalog of 8800 absorption lines between 200 and 352 cm-1. The Taylor expansion coefficients for evaluating the energies of the levels involved in the transitions are also given. All of the lines occurring in the 200-352 cm-1 region correspond to transitions between torsionally excited states. Some forbidden lines (Δn ≠ 0; ΔK = 0), indicating state mixings, have been found. © 1992.
