Investigation of the Spin-Orbit Perturbation of the 6¹Π State in KLi Molecule

Abstract

Strong perturbation in the 61 Π state of the 39 K 7 Li molecule is analysed. The perturbing state is identified as 3 3 ∆ on the basis of experimental observations aided by comparison with recent theoretical calculations. Possibilities of accessing triplet states of KLi via the 6 1 Π ∼ 3 3 ∆ perturbation are discussed.

“…We also note the more recent works of Dagdigian and Wharton [3] on molecular beam electric resonance spectra, Zmbov [4] et al who demonstrate the application of the mass spectrometry method, and Engelke et al [5] on high-resolution laser excitation spectra. Quite recently, a notable series of experiments on the KLi system were performed by the Warsaw group with different coworkers [6][7][8][9][10][11][12][13][14][15][16][17][18]. Primarily using Doppler-free polarization labeling spectroscopy, they reinvestigated earlier spectra of band systems with ground and low-lying excited states.…”
