Publisher:Ohio State University
An improved systematic organization of non-degenerate perturbation theory and the contact transformation of the hamiltonian will be presented which facilitates the determination of the higher-order portions of the rotation-vibration energy for a molecule. The discussion will include application of the method of calculation of the energies of a rotating vibrating diatomic molecule through sixth order of approximation and comparison with Dunham's result obtained by the WKB method.
