Absorption Spectroscopy of (8,1) Band in d^3△-a^3П System of CS Radical
The CS radical was generated by discharging the mixture gas of CS2 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 t...

Summary: | The CS radical was generated by discharging the mixture gas of CS2 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 d^3△-a^3П (8,1) band, in which eighty-three transitions were first observed. A set of improved molecular constants for the d^3△(v=8) and a^3П(v=1) levels were determined by a non-linear least-squares fitting of all the lines to the effective Hamiltonian. |
