Accurate ro-vibrational energies are obtained by means of a generalized pseudospectral method that offers an optimal, non-uniform discretization of the radial grid. Both s-wave ($\\ell=0$) and rotational ($\\ell \\neq 0$) states for low and high quantum numbers are calculated for four representative diatomic molecules, namely H$_2$, LiH, HCl and CO. First nine states belonging to a maximum of $n, \\ell =2$ are computed with good accuracy, along with nine other h","authors_text":"Amlan K.
