Abstract

The spectrum of CS⁺ cation was recorded in the 12,235-12,600 cm^-1 region by employing optical heterodyne velocity modulation absorption spectroscopy. In combination with simultaneous measurement of optical heterodyne concentration modulation absorption spectroscopy, the spectral lines of CS⁺ blended with the neutral CS lines were identified and extracted from the observed spectra. One hundred and eighty-two spectral lines of CS⁺ were assigned to the (2, 1) band in the A² _i-X²Σ⁺ system and the improved molecular constants of the upper level (υ = 2) in the A²_i state were derived by nonlinear least squares fitting.
