Methyl radicals, CH3, are vapor deposited in solid CH4 on a substrate at Tdep=4.2 K. EPR spectra of the radicals are taken in the temperature range Trec=1.4-4.2 K. The spectra processing, including intensity measurement of the forbidden electron-proton transitions and line shape analysis of the allowed transitions, reveals correlation of the orientational motions of the trapped radical and the nearest matrix molecules. Keywords: electron paramagnetic resonance, matrix isolation, methyl radical, solid methane, molecular rotation.
