Abstract
Tunable vacuum ultraviolet radiation (in the range 142.7-146.7 nm) from a novel laser source was used to probe the electronic excitation spectrum of cold carbon monoxide molecules in a supersonic noble gas jet. Rotationally resolved spectra of 12C16O,13C16O, as well as the rare but astronomically important 12C18O and 12C17O isotopomers, were recorded. Evidence was obtained for the formation of CO-containing van der Waals complexes in the jet.
