LIF dispersed emission spectra and characterization of ZnRg (Rg = Ne, Ar, Kr) ground-state potentials

Abstract

Laser-induced fluorescence dispersed emission spectra recorded using the C 1 Π 1 ( υ ′ ) → X 1 Σ 0 + transition in ZnKr, ZnAr and ZnNe complexes are reported. The complexes were produced in a continuous free-jet beam crossed with a pulsed dye-laser beam. The spectra were recorded using a spectrograph equipped with CCD camera. The recorded profiles displayed characteristic Condon internal diffraction patterns. The patterns consisted of reflection type continuous features corresponding to bound → free transitions and bound → bound transitions. In simulation of the spectra, M–S(9.09, 7.81), M–S(10.86, 10.32) and M–S(14.49, 8.91) Maitland–Smith M–S( n 0, n 1) functions were found to represent the repulsive walls of the X 1 Σ 0 + -state potentials of ZnKr, ZnAr and ZnNe, respectively. The obtained results were compared with available experimental and theoretical representations of other studies.
