Nonadiabatic effects in the collision of F(²P) with H ₂(¹Σ_g⁺). II. Born-Oppenheimer and angular momentum coupling in adiabatic and diabatic representations

Abstract

The matrix elements necessary for the description of electronic interactions between the 1 2A′, 2 2A′, and 2A″ surfaces of FH2 are evaluated from Born-Oppenheimer states. It is shown that these couplings are handled most appropiately in a diabatic basis. The transformation between adiabatic and diabatic bases is explicitly obtained.
