Abstract
The triplet and singlet state properties of the title compound are reported: nitroxyl free radicals and oxygen enhance the triplet yield significantly; electron transfer from the singlet excited state to methyl viologen in acetonitrile produced the corresponding free radicals which recombine with second-order kinetics.
