    • For this potential there are some states for which one frequency is an integer multiple of the other, which causes the expansion to diverge. The eigenvalues for these states could be obtained from degenerate perturbation theory; see J. O. Hirschfelder, W. Byers Brown, and S. T. Epstein, Adv. Quantum Chem. 1, 255 (1964).
