Ab initio potential energy surface and rotationally inelastic collisions of hydroxide of lithium (LiH) with argon (Ar): State-to-state inelastic rotational cross section

► The ab initio potential energy surface (PES) for the LiH(X1Σ+)-Ar(1S) have been calculated. ► The cross sections with the close coupling approach have been calculated. ► We found that the magnitude of cross section for the first levels transitions is the bigger one. ► We have found a good agreement with the earlier experiment one and calculations.
