Microwave Spectroscopy of Weakly Bound Molecular Complexes
The pure rotational high resolution microwave spectra of weakly bound molecular complexes are discussed. These complexes, consisting of a polar linear molecule and a rare gas atom or other molecule as the bound partner, have binding energies ranging from 0.2 to 6.0 kcal/mole. Formation of the complexes is achieved by a molecular free jet expansion of the monomeric components in an inert carrier gas. The expanding gas is directed into a Fabry-Perot cavity where the rotational transitions of the species of interest are excited with a microwave pulse. The subsequent coherent molecular emission can be detected and analyzed to yield structural and electronic information about the complex.
