Outline of Final Research Achievements

In this study, we have developed a system for detecting photo-induced phenomena on solid surfaces by in-situ nuclear magnetic resonance (NMR) under light illumination in a wide range of temperatures based on the existing optical pumping NMR system developed by ourselves. More specifically, we have developed: (1) sample holders and their mount systems attached to the head of the probe installed in the vacuum chamber of the cryostat, which allow effective sample cooling under the light illumination, (2) an optical fiber system that delivers light from the light source to a sample at the probe head, and (3) a system that enables synchronization of the light illumination with the rf-pulses for NMR through the control of the output of the light source with the NMR spectrometer.
