Variational Calculation of the Lower Vibrational Energy Levels of the Ammonia Molecule

The calculation of the lower-lying vibrational energy levels of the ammonia molecule, in particular those associated with the inversion motion, has been the focus of many investigations [1 — 5 ] . The inversion motion usually has been separated from the other degrees of freedom; thus the parameters of a double minimum potential have been adjusted so that… CONTINUE READING
