WebOct 14, 2024 · Mathematical justification of the Born-Huang expansion in the derivation of the Born-Oppenheimer Approximation. Ask Question Asked 1 year, 5 months ago. … The Born–Huang approximation (named after Max Born and Huang Kun) is an approximation closely related to the Born–Oppenheimer approximation. It takes into account diagonal nonadiabatic effects in the electronic Hamiltonian better than the Born–Oppenheimer approximation. Despite the addition of correction terms, the electronic states remain uncoupled under the Born–Huang approximation, making it an adiabatic approximation.
