Several bands in a new electronic transition of tungsten sulfide, WS, have been recorded at Doppler-limited resolution using intracavity laser spectroscopy with Fourier-transform detection (ILS-FTS). WS molecules were produced in the plasma discharge of a W-lined Cu hollow cathode in the presence of a gas mixture containing approximately 70% Ar and 30% H2, with a trace amount of CS2at a total pressure of 1 torr. The (0,0), (1,0), (2,0), (1,1), (2,1), and (3,1) bands of the [15.05]0+–X3Σ–(0+) transition of WS were observed. Line positions for the four major isotopologues (182W32S,183W32S,184W32S, and186W32S) of the (0,0), (1,0), and (2,0) bands were used in the fit. The WS bands were analyzed using PGOPHER, with previously determined constants for theX3Σ–(0+) ground state [Harmset al.,J. Mol. Spectrosc.374, 111,378 (2020)] held fixed in the fit. A perturbation was observed in the (0,0) band which appears to be caused by an electronic state that has not been observed. Molecular parameters for the newly identified excited state are presented.
