Phrase: Born–Oppenheimer approximation | Statement: [Franck–Condon principle, basedOn, Born–Oppenheimer approximation]

Target entity: Born–Oppenheimer approximation
Context triple: [Franck–Condon principle, basedOn, Born–Oppenheimer approximation]

• A. Born–Oppenheimer approximation chosen
  The Born–Oppenheimer approximation is a fundamental method in molecular quantum mechanics that simplifies calculations by treating nuclear motion as much slower than electronic motion, allowing their behaviors to be separated.
• B. Franck–Condon principle
  The Franck–Condon principle is a rule in molecular spectroscopy that explains the intensity distribution of vibronic transitions by assuming electronic transitions occur much faster than nuclear motion, making vertical transitions between vibrational states most probable.
• C. Rayleigh–Schrödinger perturbation theory
  Rayleigh–Schrödinger perturbation theory is a fundamental method in quantum mechanics for approximating the energies and states of a system by treating interactions as small corrections to an exactly solvable problem.
• D. Feynman–Hellmann theorem
  The Feynman–Hellmann theorem is a result in quantum mechanics that relates the derivative of an energy eigenvalue with respect to a parameter in the Hamiltonian to the expectation value of the corresponding derivative of the Hamiltonian.
• E. Born–Huang expansion
  The Born–Huang expansion is a quantum mechanical method that systematically improves upon the Born–Oppenheimer approximation by including couplings between electronic and nuclear motions in molecular systems.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
