Observation of spin dynamics under ultra-high magnetic fields up to 30 T and the analysis of chemical reactions in nano-structured materials

Abstract

Magnetic fields often affect the dynamics and yields of photochemical reactions when radical pairs are involved as chemical intermediates. Magnetic field effects (MFEs) studies provide valuable information on the mechanisms of the chemical reactions. To investigate MFEs, we have developed bitter-type magnets to generate the ultra-high magnetic field, transient absorption spectroscopy, and numerical analysis procedures. In this article, we present the basics of MFEs and their application to the analysis of chemical reactions in nano-structured material. We also emphasize the importance of the MFEs in organic spintronics and in the development of organic devices.
