Anisotropy of 2-Norbornyl Radical Reorientational Dynamics in the Plastic Phase of Norbornene as Determined by ALC-μSR

Avoided level crossing muon spin resonance effects are observed with polycrystalline norbornene in its plastic phase and analysed in terms of axial hyperfine anisotropy. The results agree with those of previous single crystal measurements. It is shown that the technique is sensitive to the detection of small anisotropies, and that it is ideally suited for the study of reorientational dynamics in polycrystalline or amorphous environments.
