Abstract

The CS radical was generated by discharging the mixture gas of CS ₂ and Helium. The Doppler limited spectra of CS were recorded in the region of 12350-12950 cm^-1 using optical heterodyne concentration modulation absorption spectroscopy. Three hundred and twenty-six lines were recorded and assigned to the d³Δ-a³Π (8,1) band, in which eighty-three transitions were first observed. A set of improved molecular constants for the d³Δ(v=8) and a³Π(v=1) levels were determined by a non-linear least-squares fitting of all the lines to the effective Hamiltonian.
