Research Abstract

We have prepared mm- and submm-wave sources to extend the applicability of the double resonance spectroscopy, and applied the method for the studies of molecular complexes and short lived species. We have also developed a computer system for the predictions of molecular spectra and analyses of the observed spectra. So far, we have reported results of Ar, Ne-NO and Ne, Kr-OH as interesting and fundamental atom-diatom systems. Observations of H_2CO_3 and HOCO have also been reported, both of which have interesting internal motions.
