204. PERTEN: One-Dimensional Vibrational Energy Levels by Perturbation

by Thomas T. Holloway, Texas Tech University, Lubbock, Texas 79409

Complete program calculates energy levels for potentials which can be expanded in the form:

V(X) = Co + Y2 (x2 + 4 k3x3 + 4 k4x4 + 4 k5x5 + ...)

The program sums the energy level expression given in J. E. Kilpatric, J. Chem. Phys., 30, 801 (1959), extending the formula to include tenth-order perturbation on x3 and all other terms which contribute about that much more to the energy. This includes contributions from all terms through x12 in the expansion of the potential.
