摘要: Abstract Solid-state varible-temperature/magic angle spinning(VT/MAS) 1 H NMR measurements were carried out on deuterated polyethylene. From these experimental results it was found that the chemical shift induced by conformational and morphological changes of polyethylene sample is within linewidth ≈ 0.5 ppm. Furthermore, from MAS/dipolar decoupling experiments resonance frequency proton varies linearly with inverse square deuterium power. This finding discussed theoretically.
