MOLECULAR SPECTROSCOPY IN LIQUID RARE-GASES

Publisher:Ohio State University
Many simple molecules dissolve in liquid argon, krypton and xenon. The use of pressures up to 15 atm. extends the liquid ranges of the rere-gases so that they form a useful set of solvents over the continuous temperature range $-182^\circ$ to $-55^\circ$ C. These solvents have a tremendous advantage over other low temperature solvents in that they are very simple, are chemically inert, and are transparent from the vacuum ultraviolet through the ultraviolet, the visible, and the infrared regions of the spectrum. A low temperature cell employing barium fluoride windows and indium metal gaskets has been built and is being used for the study of rotational, vibrational and electronic motions of molecules in liquid rare-gases. Typical spectra and their interpretation will be discussed.
