Abstract
Laser-induced fluorescence excitation spectra of jet-cooled NiCl molecules were recorded in the energy range of 12900–15000 cm−1. Six vibronic bands with rotational structure have been observed and assigned to the [13.0]2Π3/2(ν'= 0–5)-X2Π3/2(ν''=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.
