Very accurate results are obtained for \\emph{both low as well as high} states by a non-uniform optimal discretization of the radial Schr\\\"odinger equation. Excellent agreement with literature data is observed in \\emph{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 four representative diatomic molecules (H$_2$, LiH, HCl, CO).
