Muon spectroscopy of a 12-phosphatetraphene with extremely efficient radical trapping properties by Shigekazu Ito, Kohei Yasuda, Keisuke Ishihara, Victoria L. Karner, Kenji M. Kojima, Iain McKenzie

“…This muoniated radical was produced by the diffusion-controlled regioselective addition of muonium (Mu = [µ+e–]) to the sp2-hybridized phosphorus atom. The assignment of the muoniated radical structure was confirmed by observing a resonance due to the I = 1/2 (31P) nucleus in a muon (avoided) level-crossing resonance (µLCR) spectrum. …”
