Algebraic models rotational spectroscopy

It would be excessive to include in this article a comprehensive treatise on rotational molecular spectroscopy. It is, however, worthwhile to address this important subject for the purpose of demonstrating what kind of theoretical constructions can be handled within the algebraic framework. So far, most applications of algebraic models have been dealt with vibrational rather than rotational spectroscopy. However, it is only a matter of time before the algebraic treatment is applied to rotational spectroscopy since it has a unique association with the three-dimensional model.
