Abstract
Comprehensive spectroscopic study of CdKr van der Waals complex in its Rydberg electronic energy state E3Σ1+(5s6s3S1), using OODR process from the ground X1Σ0+(5s21S0) state via the intermediate A30+(5s5p3P1) or B31(5s5p3P1) states, is presented. Detection of the E3Σ1+,υ′←A30+,υ″ and E3Σ1+,υ′←B31,υ″ 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 E3Σ1+state exhibits double-well structure with inner (deeper) E3Σ1in+ and outer (shallower)E3Σ1out+ wells. More reliable characterization of both wells using inversed perturbation approach (IPA) methodology is achieved.
