Abstract
For a diatomic molecule, when the Dunham coefficients Y20 is negative, all fea- tures of potential-energy curve can be reproduced. When Y20 is positive; it is not possible to reproduce all features of the potential-energy curve. However, turning points for some lower vibrational states can be obtained.
