Résumé :

Spectra of the weakly-bound van der Waals complexes Ar-CS2, Ne-CS2, and He-CS2 are studied in the region of the CS2 ν3 fundamental band (≈1535 cm-1) using a tunable diode laser to probe a pulsed supersonic expansion from a slit jet nozzle. He-CS2 is also observed in the ν1 + ν3 region (≈2185 cm-1). These are the first reported spectra for rare gas-CS2 complexes, which are shown to have T-shaped structures similar to their CO2 analogs but with intermolecular separations which are 0.2-0.3 Å greater. © 2012 Elsevier Inc.
