タイトル(掲載誌)APPLIED MAGNETIC RESONANCE
一般注記To investigate the experimental technique and the high magnetic field effect in the dynamical nuclear polarization (DNP) experiments, the X-band 1H-DNP and the high power sub-THz wave irradiation experiments have been performed on bis-diphenylene-phenyl-allyl (BDPA)-doped toluene solution at room temperature. We have established the sample-shuttle X-band DNP experimental system, and investigated the external magnetic field, the microwave power and 1H-T_1 ^-1 dependences of Overhauser enhancement factor (e). A maximal signal enhancement of approximately –19 has been observed. As for the sub-THz wave experiments, we have constructed the NMR and ESR measurement system for the experiments under the magnetic field of ~10.7 T, with a high power light source gyrotron CW-I (TE_<22,8> mode, f~299.23 GHz). When the high power sub-THz wave of a gyrotron was irradiated on the toluene solution in order to confirm the evidence of DNP, the sample has evaporated due to the electromagnetic (EM) wave heating.
