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