| Research Abstract |
Toward size-selective spectroscopy of the water clusters, the pulse switch system to generate a high voltage pulse was built and applied to the time-of-flight mass spectrometer. The rare gas cell and the mercury cell were made for generation of the vacuum-ultraviolet light. To demonstrate the spectroscopy, we have performed the size-selected infrared spectroscopy for clusters of hydrogen sulfide (H2S), as the model of water clusters. The proton donor ability of H2S has been revealed through the size-selective infrared spectroscopy of its clusters.With these home-made gas cell and high voltage pulse source, the vacuum-ultraviolet pulse field ionization spectroscopy was developed. These methods developed in this study will be applied to the clusters of water.
