Abstrakt: Far-infrared-absorption spectroscopy is used to investigate the low-frequency (<=100 cm-1) intermolecular interactions in liquid methanol. Using an intense source of far-infrared radiation, modes are elucidated at approximately 30 and 70 cm-1 in the absorption spectrum. These modes are believed to arise from intermolecular bending and librational motions, respectively, and are successfully reproduced in an ab initio molecular-dynamics simulation of methanol.
