摘要：
A polarization labelling spectroscopy technique was used to investigate the A(1)Sigma(+) <- X-1 Sigma(+) band system of the (LiCs)-Li-7 molecule in a heat-pipe oven. All 27 observed vibrational levels of the A state were found to be subject to strong perturbations assigned to interaction with the b(3)Pi (0) state. The deperturbation analysis provided molecular constants of the A and b states and a value of the electronic part of the spin-orbit interaction matrix element b(3)Pi(0)vertical bar H-so vertical bar A(1)Sigma(+).
