Abstract
This study uses quantum mechanical and semi-classical SCF theory to determine molecular vibration energies, and compares the results to values obtained by more accurate quantum mechanical and semi-classical methods. The SC Hamiltonian retains Coriolis and anharmonic potential energy terms while the QM Hamiltonian retains these and the Watson term -$- \frac{h^{2}}{8}\Sigma $ax. These numerical experiments provide a meaningful test of semi-classical SCF and quantum mechanical SCF methods, and are being done by senior students (D.L., W.R., and L.P.) as undergraduate research projects in physical chemistry at Allegheny College.
