Intensity determinations for an atlas of the infrared spectrum of methanol

Conference ·
OSTI ID:456924
An atlas of the spectrum of methanol has been prepared for publication. The atlas includes a listing of 37 000 transitions and a plot of the absorption spectrum from 20 to 1258 cm{sup -1}. The plotted spectrum segments come from measurements made at various values of pressure, path length and resolution, so that the transmittance values are not comparable. A procedure was set up to derive line intensity parameters S for each line. A balance was sought between accuracy of intensity values and effort involved, considering the extensive overlaps in the spectrum and pressure broadening variations as well as the number of transitions.
