carbon‐13 spin–lattice and spin–spin relaxation rates as well as nuclear Overhauser enhancement (NOE) were combined with selected proton cross‐relaxation measurements for sucrose in a viscous cryosolvent, D2O–DMSO, at several magnetic fields and two temperatures. The results, which were outside the extreme narrowing regime, were interpreted using the Lipari–Szabo formalism. All the carbon relaxation data
碳 13 自旋晶格和自旋自旋弛豫率以及核 Overhauser 增强 (NOE) 的测量与选定的质子交叉弛豫测量相结合,在粘性冷冻溶剂 D2O-DMSO 中,在几个磁场和两个温度下测量蔗糖. 使用 Lipari-Szabo 形式主义解释极端缩小范围之外的结果。所有碳弛豫数据和质子交叉弛豫率都给出了一致的描述,表明两个糖残基显示出相似且高度有限的内部迁移率,而羟甲基的迁移率更高。我们的碳和质子组合数据并未证明蔗糖中糖苷键的灵活性。版权所有 © 2000 John Wiley & Sons, Ltd.
