High-Resolution Study of the Near-Infrared A2Pi1/2-X2Sigma+ Transition of YS.
A high-resolution excitation spectrum of gaseous YS has been recorded by laser excitation spectroscopy in a supersonic molecular beam. The YS molecules were produced by the reaction of laser-ablated yttrium atoms with CS2. The band of the A 2Pi1/2-X 2Sigma+ transition near 750 nm was rotationally analyzed, and a set of molecular constants is given for both electronic states. Copyright 1998 Academic Press.
