✦ Synopsis

Solid-state varible-temperature/magic angle spinning(VT/MAS)

' H NMR measurements were carried out on deuterated polyethylene. From these experimental results it was found that the 'H chemical shift induced by conformational and morphological changes of the polyethylene sample is within the linewidth of = 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. 0 1997 Elsevier Science B.V.

Spinosin, a C-glycoside flavonoid, was isolated from the plant Desmodium tortuosum (Sw.) DC. The 1 H and 13 C NMR data acquired at room temperature exhibited doubling of signals, suggesting the presence of two rotamers in solution. Variable-temperature 1 H NMR experiments confirmed this hypothesis.

## Abstract In order to obtain some insight into the structure of an ultrahigh‐molecular‐weight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to βˆ’108Β°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co
