Laser spectroscopy of CdKr molecules in ultraviolet region.
Excitation spectra of the A0+(5(3)P1)<--X0+(5(1)S0), B1(5(3)P1)<--X0+ and D1(5(1)P1)<--X0+ transitions as well as a fluorescence spectrum of the D1(v') = 16 --> X0+ transition in CdKr van der Waals molecule has been recorded in an experiment of a continuous supersonic molecular beam crossed with a pulsed dye laser beam. A rigorous analysis of the excitation spectra based on Birge-Sponer and LeRoy-Bernstein methods aided with a computer calculation, utilizing a program of near dissociation expansion lead to the X0+- and improved A0+-, B1- and D1-state characterizations. Evidence of a theoretically predicted potential barrier within the B1-state well was found and discussed with regard to the latest result of ab initio calculation. An analysis of bound-bound and bound-free parts of the fluorescence spectrum confirmed a v'-assignment and indicated that Morse and Maitland-Smith M-S (n0, n1) functions are adequate representations of the bound well and repulsive wall of the X0+-state potential energy curve, respectively. All spectroscopic characteristics obtained in this work are compared with newest theoretical studies of this complex.
