気相分子イオンの核磁気共鳴分光装置の開発
Mass spectroscopic techniques are now used extensively in various research fields. Since this method gives information only on mass number, the structures of the parent molecular ions are analyzed with an aid of the computer simulations for the fragment ions. On these backgrounds an extension of the nuclear magnetic resonance (NMR) technique to gas-phase molecular ions, which enables us to obtain rich information on the structure of target ions with a mass-spectral sensitivity, becomes increasingly important in both fundamental and applied sciences. To develop the NMR detection technique for the gas-phase molecular ions, we are developing a gas-phase NMR apparatus based on a Stern-Gerlach type experiment in a strong magnetic field. We present the experimental procedures for the key techniques to detect the NMR by the present method such as the preparation of cold ions in a strong magnetic field, and a RF magnetic field excitation of these ions. Recent progress in the development of this apparatus will be discussed.
