Research Abstract |
We have constructed a new NMR probe for the measurement of solid state NMR spectra under the electric field. The high-power amplifier was used for the observation of the spectra. The sample in the dyfron plate vessel. The sample stage was mounted in the goniohead so that the stage can be rotated. Consequently, the electric field can be applied to the sample in the region of -90 - +90°against the magnetic field. To avoid an evolution of heat, cooled air was supplied to the stage by the tube. High-voltage rapid electric amplifier was installed, which can apply direct voltage of 0-500 V to the sample. Using the probe, we have measured ^<13>C NMR spectra of 4-cyano-4'-n-pentylbiphenyl (5CB), which shows a nematic liquid crystal phase at room temperature, by stepwise increase of a electric field. The obtained spectra are found to be in good agreement with previous reports on a local motion and an electronic structures of 5CB. In addition we have used the probe to characterize microporous coordination polymers with guest inclusion ability.
