Transient radical species generated in the photolysis of 2-(4-nitrophenyl)-1H-indoly-3-methyl (NPIM) derivatives were studied using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) spin trapping studies. The structures of the DMPO spin adducts were determined through electron paramagnetic resonance spectroscopy, mass spectrometry, and quantum chemical calculations. The results revealed homolytic bond cleavage in the photolysis of NPIM derivatives.
