Spectroscopy of CdKr van der Waals complex using OODR process: New determination of the E3Σ+1(5s6s 3S1) Rydberg state potential


Comprehensive spectroscopic study of CdKr van der Waals complex in its Rydberg electronic energy state E3Sigma1+(5s6s 3S1), using OODR process from the ground X1Sigma0+(5s21S0)state via the intermediate A30+(5s5p 3P1) or B31(5s5p 3P1)states, is presented. Detection of the E3Sigma1+,v' <- A30+,v" and E3Sigma1+,v' <- B31,v" transition frequencies with higher accuracy and spectrally narrower laser extends previous analyses and simulations of laser induced fluorescence (LIF) excitation spectra. Potential energy curve of the E3Sigma+1 state exhibits double-well structure with inner (deeper) E3Sigma1+in and outer (shallower)E3Sigma1+out wells. More reliable characterization of both wells using inversed perturbation approach (IPA) methodology is achieved.
