Overview of photo-CIDNP. A) Instrumental setup. B) Radical pair mechanism of photo-CIDNP in liquids. M* denotes the spin-polarized molecule of interest. C) 2D 13C-PRINT photo-CIDNP spectra of the σ32 peptide (13-amino acids, 20 μM, 600 MHz spectrometer) in the absence and presence of catalytic amounts of the photo-CIDNP-enhancing NR-GO-CAT tri-enzyme system [95].
