Very accurate results are obtained for both low as well as high states by a nonuniform optimal discretization of the radial Schrödinger equation. Excellent agreement with literature data is observed in both s-wave and rotational states. Detailed variation of energies with respect to potential parameters is discussed. Application is made to the ro-vibrational levels of representative diatomic molecules (H2, LiH, HCl, CO). Nine states having n,ℓ=0,1,2 are calculated with good accuracy along with 15 other higher states for each of these molecules. Variation of energies with respect to state indices n, ℓ show behavior similar to that in the Morse potential. Many new states are reported here for the first time. In short, a simple, accurate, and efficient method is presented for this and other similar potentials in molecular physics. © 2013 Wiley Periodicals, Inc.
