Modeling of light asymmetric rotor spectra to microwave accuracy

By the early 1970’s the combination of Watson’s development of a reduced centrifugal distortion Hamiltonian and advances in spectroscopic methods made it possible to model (with empirical extensions to higher order) asymmetric rotor spectra to microwave accuracy. This made possible modern spectral catalogs like those of JPL and Koln.
