6) high resolution solid state 13C NMR 固体高分辨~(13)C谱补充资料:固体高分辨核磁共振 固体中存在如化学位移、偶极矩、间接自旋耦合、四极矩、核与电子的自旋、 自旋-转动等各向异性相互作用,而且固体中的核是固定不动的,不像液体中的分子作快速无规运动使各向异性相互作用的统计平均值为零,所以固体核磁...
13C NMR and EPR methods are employed to quantitatively determine the composition of thermoplastic vulcanizates (TPVs) based on ethylene-propylene-diene rubber (EPDM), polypropylene (PP) and extender oil, with and without talcum filler. The oil has a strong influence on both the processing and th...

1.Crystalline structure of bamboo fiber was investigated by solid-state 13C-CP/MAS NMR spectroscopy,and was compared to ramie,flax and cotton.利用固态核磁共振碳谱分析研究了天然竹纤维的结晶结构,并与常规的天然纤维素纤维苎麻、亚麻和棉纤维进行了比较。 2)Solid-state MAS ~(27)Al NMR固态核磁共振谱 ...
Solid-state 13C NMR has been important to overcome analysis difficulties arising from the low solubility of carbonaceous materials. Its use provides accurate information about these materials. In this work, resonance techniques involving magic angle spinning with cross-polarisation (CP/MAS) or single ...

The structure and molecular motion of metallocene-catalyzed linear low-density polyethylenes (MLLDPE) have been investigated in the α relaxation temperature region by solid-state 13C NMR spectroscopy. Fully relaxed dipolar decoupling (DD)/MAS 13C NMR spectra are well resolved into the crystalline,...
