Abstract
We report on the observation of a gerade Rydberg electronic energy state of Cd2 van der Waals (vdW) complex vibrationally cooled in a free-jet expansion beam. Cd2 in the beam were excited from the X10g+(51S0) ground via the b30u+(53P1) intermediate to the final gerade state using optical–optical double resonance (OODR) method. A pronounced vibrational progression with partly resolved isotopologue components was recorded and analyzed. The analysis of isotopic separation indicated the excitation to high vibrational levels (υ′≈50). A comparison with the result of ab initio calculations reveals, that Cd2 was most probably excited to the 31g -state correlating with the 63S1 atomic asymptote.
