Abstract
By going beyond the Born-Oppenheimer approximation and treating the non-adiabatic coupling terms (NACTs) as equivalent to a frictional force in a molecular system, the classical equations of motion are solved for a test case of (DH2)+. Using an ab initio potential energy surface for the ground electronic state and its NACTs with the first excited state of (DH2)+, it is shown that (D+, H2) collisions are slowed enough to result in trapping and formation of a stable DH2+.
