In turn, the resulting potential energy curves are used to determine the radial functions describing the spin-rotation and hyperfine energy patterns of the spin-rovibrational energy levels by morphing/fitting their ab initio/empirical approximants. The resulting functions allow for reliable predictions for untested spectral regions, provide a base for testing the impacts of external fields on the measured spectral transitions, and allow for accurate estimations of the mass sensitivity of the hydroxyl spectral transitions appearing as suitable probes of a cosmological variability of the electron-to-proton mass ratio.
