In the algebraic approach to the Born-Oppenheimer approximation, equations in the algebra of physical operators yield the induced vector and scalar potentials; eigenstates are never needed. The ''slow'' variables need not commute. In the classical analog, the Poisson bracket replaces the commutator. A non-adiabatic extension is indicated.
