Structural analysis of oligosaccharides using 3D NMR.
It is possible to analyze the structure of complex organic compounds with overlapping peaks.
In the structural analysis of organic compounds using NMR, two-dimensional NMR is generally used in addition to one-dimensional NMR (1H-NMR and 13C-NMR) to confirm the correlations between peaks in one-dimensional NMR, allowing for the assignment of peaks and determination of the compound's structure. However, in compounds such as sugars that contain many similar structures, peaks can overlap even in two-dimensional NMR, making analysis difficult. In such cases, three-dimensional NMR is effective. This document presents examples of applying three-dimensional NMR using oligosaccharides as model compounds.
