The Nuclear Spin of the Hydrogen Molecule in the Liquid and Solid States

Target entity: The Nuclear Spin of the Hydrogen Molecule in the Liquid and Solid States
Context triple: [Carl Woese, doctoralThesis, The Nuclear Spin of the Hydrogen Molecule in the Liquid and Solid States]

• A. Longuet-Higgins theorem in molecular symmetry
  The Longuet-Higgins theorem in molecular symmetry is a fundamental result in theoretical chemistry that relates molecular symmetry properties to electronic state degeneracies and the occurrence of phenomena such as the Jahn–Teller effect.
• B. Herzberg–Teller approximation
  The Herzberg–Teller approximation is a refinement in molecular spectroscopy that accounts for vibronic coupling by allowing electronic transition dipole moments to depend on nuclear coordinates, explaining intensity in otherwise forbidden transitions.
• C. The Nature of the Chemical Bond
  The Nature of the Chemical Bond is a landmark chemistry book by Linus Pauling that systematically explains chemical bonding using quantum mechanics and became one of the most influential scientific texts of the 20th century.
• D. Langevin theory of paramagnetism
  The Langevin theory of paramagnetism is a classical statistical model that explains how the magnetization of paramagnetic materials depends on temperature and applied magnetic field by treating atomic magnetic moments as non-interacting dipoles subject to thermal agitation.
• E. Brillouin–Wigner perturbation theory
  Brillouin–Wigner perturbation theory is a formulation of quantum mechanical perturbation theory that uses an energy-dependent effective Hamiltonian to obtain improved approximations to eigenvalues and eigenstates.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
