Analysis of the muon spin rotation (@R) data for the muonic ethyl radical CH,MucH, yields &hyperfine coupling constants in good agreement with the recent level-crossing resonance (LCR ) measurements. Other coupling constants are predicted and await confirmation by LCR. The role of hyperconjugation i

The (CH,),COMu radical forms when positive muons are stopped in pure acetone and dilute mixtures of acetone in n-hexane or water. Muonium is the precursor of the radical in dilute solution and evidently differs from hydrogen in adding readily to the carbonyl group. In micelles this addition reaction
## Abstract The copolymerization of __p__β__tert__βbutoxystyrene (1) (M~1~) and dibutyl fumarate (2) (M~2~) initiated with dimethyl 2,2β²βazobisisobutyrate (3) was studied in benzene at 60Β°C kinetically and by means of electron paramagnetic resonance (EPR) spectroscopy.
