Abstract
This study explores, both theoretically and experimentally, the photochemically induced dynamic nuclear polarization (photo-CIDNP) of 19F nuclei, the associated spin relaxation, cross-relaxation and cross-correlation effects, as well as potential applications of 19F CIDNP to protein structure and folding problems. Keywords: CIDNP, relaxation, fluorine, NMR, NOE, TR-CIDNP, tc5b, Trp-cage, GFP
