THE VISIBLE AND PURE ROTATIONAL SPECTRUM OF PLATINUM MONOSULFIDE, PTS

Numerous band systems in the visible spectral region of a supersonic molecular beam sample were detected using medium-resolution laser-induced fluorescence spectroscopy. Three of the intense band systems were recorded at high resolution and rotationally analyzed. Pure rotational transitions in the ground state of (PtS)-Pt-194, (PtS)-Pt-195, and (PtS)-Pt-196 were recorded using the pump/probe microwave optical double-resonance technique. Spectroscopic constants for the ground and three low-lying excited vibronic states have been derived. (C) 1995 Academic Press, Inc.
