The hydroxyl groups of carbohydrates are critical determinants of their conformational dynamics and intermolecular interactions but are difficult to characterize by conventional 1H nuclear magnetic resonance (NMR) approaches in solution. Here, we report a solid-state 17O NMR analysis of synthetic glucosamine with 17O enrichment at position 6. Based on magic-angle spinning and stationary spectral data obtained at varying magnetic fields in conjunction with quantum chemical calculations, we successfully estimated 17O chemical shift and electric field gradient tensors, providing benchmark for 17O NMR analyses of oligosaccharide structures.
