極低温イオンの分光法の研究：クラスター科学と質量分析の協奏的展開
Over the past 50 years clusters have evolved as a new field of matter intermediate between atoms and bulk. In the early days, mass spectrometry played a major role and the relative abundance of clusters in the mass spectra was analyzed with theory to relate to their thermodynamic stability. In early 1980, a pulsed supersonic jet and various laser spectroscopic techniques were introduced in this field including a laser vaporization method, which enables us to produce metal clusters of any element in periodic table, and as a result, cluster research became a very active area and its scope was extensively broadened. As time progressed from four decades ago, cluster science emerged as a major scientific field, enabled to the development of various advanced mass spectrometric techniques including new ion sources. In this presentation, the interplay of cluster science and mass spectrometry, especially focus on the laser spectroscopy, is firstly overviewed and then briefly discuss on a temperature-variable photodissociation spectroscopy for mass-selected small biomolecular ions and the development of a gas-phase NMR spectroscopy.
