13C NMR spectroscopy provides insight into the chemistry of carbohydrate-based ferric preparations. Specifically, it reveals whether oxygen atoms of the carbohydrate are directly bonded to the preparations' ferric centres or whether more distant interactions are present. After having validated the method ...

13C-NMR讲述.ppt,13C-核磁共振波谱法 Nuclear Magnetic Resonance Spectroscopy 一、概述 13C核磁共振波谱的原理与1H核磁共振基本相同。所有有机化合物都含有碳和氢元素,由于13C的化学位移范围(0~240)远大于H核的化学位移(0~15),因此13C核谱分辨率高。几乎每一种化学
'13C NMR Spectroscopy' is a technique that involves the use of 13C-labelled substances to study metabolic processes in living organisms, such as lipid deposits, glycogen breakdown, and glucose metabolism in different tissues like the brain. ...
