Abstract

The electronic emission spectrum of CS in the range of 9500-17500 cm-1 was recorded with 0.03 cm-1 resolution using the 1-m Fourier transform spectrometer associated with the McMath solar telescope at Kitt Peak National Observatory, Arizona, with an electric discharge in a CS2 and helium mixture. A total of more than 3400 transition frequencies for 24 d3Δ1 (v = 3-14)-a3Π0 (v = 0-2), d3Δ2 (v = 3-12)-a3Π1 (v = 0-2), and d3Δ3 (v = 3-9)-a3Π2 (v = 0-2) bands have been assigned for the vibronic structure of the near-infrared electronic emission. Thirteen of these bands were observed for the first time. The study of the Λ-doubling perturbation of the d3Δ1-a3Π0 (7-0) band allowed us to locate a vibrational level of the previously unknown 1Σ- valence state of CS (T = 40 835.5 cm-1, B = 0.597 cm-1).
