Muon spin rotation spectra for muonium isotopically substituted ethyl radicals
Abstract
The temperature dependence of the β-hyperfine coupling constant is reported for muonic radicals formed in ethene CH2CH2, [2H1]ethene CH2CHD, [2H3]ethene CHDCD2 and [2H4]ethene CD2CD2. These studies are complemented by e.p.r. observations upon the radical CH2DĊH2.
The barrier to internal rotation for the radical CHD2ĊD2 is discussed.
