Abstract: | Laser-induced fluorescence excitation spectra of jet-cooled NiS molecules were recorded in the energy range of 12200-13550 cm-1. Four vibronic bands with rotational structure have been observed and assigned to the [12.4]3∑0- -X3∑0- transition progression. The relevant rotational constants, significant isotopic shifts, and (equilibrium) molecular parameters have been determined. In addition, the lifetimes of the observed bands have also been measured. |
