During the irradiation of phenol (1) with 15 N-enriched tetranitromethane in acetonitrile, and during the reaction of 1 with 15 N-enriched nitric acid and nitrous acid, emission due to the nitration products o-and p-nitrophenol (2a, 2b) is observed in the 15 N-NMR spectra. The CIDNP effects are buil
