The lignin sample was dissolved in DMSO-d6 and also a standard Bruker heteronuclear single quantum coherence (HSQC) pulse sequence was employed with all the following acquisition parameters: spectra width 12 ppm in F2 (1H) dimension with 2048 time of domain, 220 ppm in F1 (13C) dimension with 256 time of domain, a 1.5-s delay, a 1JC of 145 Hz, and 64 scans. The central DMSO solvent peak (13C/1H at 39.5/2.49) was utilised for chemical shift calibration. Assignments of lignin compositional subunits and interunit linkage have been based on reported contours in HSQC spectra. The relative abundance of signal.
