osity-enhanced spectroscop () offers a new way to analyze complex mixtures of time-varying composition. This communication reports the use of the viscous binary solvent DMSO-/water to induce NMR spin diffusion for chemical reaction monitoring and real-time characterization of a 3-substituted 4-hydroxycoumarin derivative and its side-product.
黏度增强光谱 () 为分析随时间变化的复杂混合物提供了一种新方法。本通讯报道了使用粘性二元溶剂 DMSO-/水来诱导 NMR 自旋扩散,用于监测化学反应和实时表征 3-取代 4-羟基香豆素衍生物及其副产物。
