Recently, mass spectroscopic techniques are widely used in various research fields. Since this method gives information only on the mass number, it is used to reconstruct the structures of the parent molecular ions with an aid of the computer simulations for the fragment ions. Under these circumstances, a new extension of the nuclear magnetic resonance (NMR) technique to the gas-phase molecular ions, which enables us to obtain rich information on the structure of the target ions with a mass-spectral sensitivity, becomes increasingly important in both fundamental and applied sciences. To extend the NMR detection technique to the gas-phase molecular ions, we are developing a gas-phase NMR apparatus based on a Stern-Gerlach type experiment in a Penning trap. We present the outline of the apparatus under development, and also the experimental procedures for the key techniques to detect the NMR such as the formation of cold ions, and the magnetic field excitation of these ions with the saddle-type RF coils.
