| Outline of Final Research Achievements |
We studied the generalization of dynamic nuclear polarization using electron spins in the photo-excited triplet state (triplet DNP) for NMR application. To evaluate its electron spin properties, an electron spin resonance spectrometer was developed. We also prepared a liquid NMR probe capable of measurement in a high magnetic field and a highly uniform magnetic field to show that triplet DNP can be used for chemical analysis applications. We have succeeded in increasing the number of molecular species that can be highly polarized by triplet DNP using eutectic, which is a new sample preparation method. Rose bengal was adopted as a new highly polarization source, but we did not measure electron spin signals at near liquid nitrogen temperature.
