Ab initio electronic structure theory provides potential energy and dipole moment surfaces that can be used to compute rovibrational term values and transition moments, either by normal mode analysis followed by rovibrational perturbation theory or through variational calculations. The accuracy of the theoretical spectra thus generated depends on the level of electronic structure theory and the nuclear motion treatment applied. This review surveys the currently available theoretical methods and their accuracy. Case studies are discussed to illustrate the present state of the art.
