摘要：

We have studied the X (1)Sigma(+) and B (1)Pi states of (LiRb)-Li-7-Rb-85 using Laser Induced Fluorescence (LIF) Spectroscopy and Fluorescence Excitation Spectroscopy (FES). We extract molecular constants for levels v '' = 0-2 of the X (1)Sigma(+) state and levels v' = 0-20 of the B (1)Pi state. For the B (1)Pi state, we have observed rotational perturbations in the e-parity component of the v' = 2 level, and determined the dissociation energy. We discuss implications of our measurements in finding efficient photoassociation pathways for production of ultra-cold ground state LiRb molecules, and their detection via state selective ionization.
