Muoxyalkyl radicals (R 2 C • —O—Mu) were observed by transverse‐field muon spin rotation (TF‐μSR) spectroscopy during irradiation of liquid compounds containing different carbonyl functions (aldehyde, ketone, ester, amide, anhydride) with spin‐polarized positive muons. These radicals may be viewed as formal adducts of the light hydrogen isotope muonium (μ + e − ) arising from its addition to the oxygen atom of the CξO bond: C • —O—Mu. Comparison is made with the related protium analogues, C • —O—H.
