Abstract
Effective potential energy curves of the ground electronic states of the isotopomers of nitric oxide (NO) are constructed by morphing the best empirical potential energy function from the literature within the framework of the Jen c v reduced potential energy curve (RPC) approach. The morphing is performed by fitting the RPC parameters to available experimental ro-vibrational data.
Subsequently, the resulting potential energy curves are used to determine the radial property functions describing the spin-orbit, fine and hyperfine energy patterns of the spin-ro-vibrational energy levels by morphing their ab initio approximants or by a direct fitting to experiment. The resulting functions enable reliable predictions outside the so-far prospected energy regions and quantitative probing of the impacts of external perturbations on the observed spectra.
