Abstract

Photo-CIDNP has been observed in the amino acids tyrosine, histidine, and tryptophan and in proteins. Polarization of CIDNP enhanced NMR lines may be transferred to other lines as a result of dipolar cross-relaxation. For proteins the sign of the transferred polarization is opposite to that observed for the amino acids.
