Abstract

The effect of the potential shape on the calculation of vibrational levels of diatomic molecules is investigated in terms of the molecular parameters, obtained from its Dunham, Ogilvie-Tipping, Simons-Parr-Finlan, and Takkar approximate expansions. It is established that the last two representations provide the best reconstruction of vibrational levels from an adjustable potential.
