Fig. 4. A graphical representation of a time course analysis of the DDQ oxidation of dioxasolv beech lignin. The X-axis represents the time (in minutes) and the Y-axis represents the no per 100 C9 units for each unit calculated using semi-quantitative 2D HSQC NMR analysis. For full data and graph displaying β–O-4(G)α–OX also, see Table S4 and Fig. S9 and S10† respectively. See also Fig. S11 and S12† for full NMR spectra.
