Abstract

The vibration-rotation absorption spectra of the C3S molecule were studied using a tunable infrared diode laser spectrometer. The v1 fundamental and v1 + v5 - v5 hot bands were measured between 2046 and 2067 cm-1. The C3S molecule was produced by a glow discharge in a flowing mixture of CS2, C2H2, and He. The analysis of the measured spectral lines yielded the band origins, the rotational and centrifugal distortion constants in the upper vibrational states, and the l-type doubling constant for the v1 + v5 state. The band origins were determined to be 2058.21875(47) and 2053.03769(45) cm-1 for the v1 fundamental and v1 + v5 - v5 bands, respectively. The values in the parentheses correspond to three standard deviations.
