Paper Abstract

The infrared absorption intensities of liquid CH3OH, CH3OD, CD3OH and CD3OD at 25 degree(s)C have been measured by CIRCLE cell multiple attenuated total reflection spectroscopy and by transmission spectroscopy. The intensities are calculated from the spectra as the infrared real, n(v), and imaginary, k(v), refractive indices. The estimated accuracy is +/- 0.5% for n(v) and +/- 3% for k(v) in the regions of significant absorption. Other absorption intensity spectra are calculated from the refractive indices, and the wavenumbers and shapes of bands in the different spectra are compared. Molecular properties can be calculated from several different intensity quantities, under different degrees of theoretical approximation. The effect of these different approximations is shown to be unimportant for experimental spectra of CH3OH.
