Effective potential energy curves of the ground electronic states of isotopomers of the methylidyne radical CH are constructed by morphing accurate ab initio potential energy curves within the framework of Jenč’s reduced potential energy curve (RPC) approach. The morphing is performed by fitting the RPC parameters to available experimental ro-vibrational data. In turn, the resulting potential energy curves are used to determine the radial property functions describing the spin-orbit and 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 predicting outside prospected energy regions, and a quantitative probing of the impacts of external perturbations on the observed spectra.
