Detections and dynamics of internal motions of radicals and radical complexes with very weak bondings

我们制备了毫米波和亚毫米波源，以扩展双共振光谱的适用性，并将该方法应用于分子复合物和短寿命物种的研究。我们还开发了一个用于预测分子光谱和分析观测光谱的计算机系统。到目前为止，我们已经报道了Ar，Ne-NO和Ne，Kr-OH作为有趣的和基本的原子-硅藻系统的结果。H_2CO_3和HOCO的观测也有报道，它们都有有趣的内部运动。

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.
