Long-range coefficients for the low-lying electronic states of LiB

Dynamic electric dipole polarizabilities of Li (2S; 2P) and B (2P) are obtained by a time dependent gauge invariant method. C6 coefficients are deduced from the fit of sum-over-states functions to the dynamic polarizabilities at imaginary frequencies, in taking the first oscillator strength and transition energy values calculated at the configuration interaction level as starting points. The dispersion coefficients for the low-lying electronic states of LiB that dissociate into Li 2S(2s1)+ B 2P(2p1) and Li2 P(2p1) + B2 P(2p1) are reported.
