High resolution laser spectroscopy of the [14.9](4)Sigma(-)-X-4 Sigma(-) transition of jet-cooled CrP
The diatomic molecule, chromium monophosphide, has been studied by laser-induced fluorescence in a supersonic beam following laser-ablation of a chromium target in the presence of a small percentage of phosphine doped in helium. Two bands have been analyzed and were assigned as the 0-0 and 1-0 bands of the [14.9](4)Sigma(-)-X-4 Sigma(-) electronic transition. An excited state value of Delta G(1/2) =332.7341(16) cm(-1) was obtained. From dispersed fluorescence, ground state values of omega(e) = 408.0 +/- 2.6 cm(-1) and omega(e)x(e) = 2.2 +/- 0.6 cm(-1) were obtained. The two bands were found to be perturbed, particularly the 0-0 band, but a satisfactory rotational analysis yielded a well-determined set of molecular parameters. (C) 2007 Elsevier B.V.
