Analysis of (1, 4)-β-d-Glcp using solution-state 2D HSQC and 3D HCCH-TOCSY spectra of 13C-poplar extracted in DMSO/pyridine.

(a) 2D 1H-13C HSQC spectrum. Crossed marks show C1-6 signals of (1, 4)-β-d-Glcp assigned by 3D HCCH-TOCSY. (b) 2D 1H-1H planes at 60.2, 74.6, 79.9, 74.6, 72.7 and 62.7 (folded spectrum; 102.7) ppm of 13C, which correspond to the C6, C5, C4, C3, C2 and C1 of (1, 4)-β-d-Glcp, slicing the 3D 1H-1H-13C spectrum. Red transverse lines connect 1H-13C-13C-1H cross peaks and vertical dashed lines connect corresponding signals between 3D and 2D spectra.
