Theoretical work Carney and Porter(1977) Tennyson, Polyansky and coworkers carried out very high level ab initio calculations, and interactions between theory and experiments were often very crucial in assigning the spectra and in deriving the accurate spectroscopic constants. See for example, Polyansky and Tennyson, JCP,110, 5056(1999) See for example, Polyansky and Tennyson, JCP,110, 5056(1999)
