| Research Abstract |
Developments of vibrational spectroscopic techniques with vacuum-ultraviolet (VUV) photoionization detection enable to perform size-selective vibrational spectroscopic investigations for neutral clusters of fundamental molecules and unstable cluster cations which can be generated by the VUV photoionization. The spectroscopic methods have been developed by application of scannable coherent VUV lights. The spectroscopic principles have been demonstrated by its application to vibrational spectroscopic investigations of neutral clusters of protic molecules (ammonia, methanol, and acetic acid), acetone of an aprotic molecule, and hydrated formamide. As the results, their cluster structures have been determined. By application of the spectroscopic principle to a tandem-type quadrupole mass spectrometric system, a spectroscopic method with precise size-selection has been established for cluster cations generated by VUV photoionization. Ionization dynamics of the clusters of the protic, aprotic molecules, and hydrated formamide have been clarified by structure analyses of their neutral and cationic clusters with infrared spectroscopy.
