Abstract
For a diatomic molecule, when the Dunham coefficient Y-20 is negative, all features of the potential-energy curve can be reproduced. When Y-20 is posi tive, it is not possible to reproduce all features of the potential-energy curve. However, the turning points for some lower vibrational states can be obtained.
