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).
