✦ Synopsis

The vibration-rotation absorption spectra of the C 3 S molecule were studied using a tunable infrared diode laser spectrometer. The n 1 fundamental and n 1 / n 5 0 n 5 hot bands were measured between 2046 and 2067 cm 01 . The C 3 S molecule was produced by a glow discharge in a flowing mixture of CS 2 , C 2 H 2 , 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 n 1 / n 5 state. The band origins were determined to be 2058.21875(47) and 2053.03769(45) cm 01 for the n 1 fundamental and n 1 / n 5 0 n 5 bands, respectively. The values in the parentheses correspond to three standard deviations.
