Figure 3

1D 13C NMR spectra for modern (a) and fossil (b) Dammar polymers. Enlargements showing details of olefinic resonances (ii) are inset, as are details of the 95–65 ppm region showing details of alcohol/ether resonances, measured in CD2Cl2 (iii). See Additional file 2 for interactive NMR spectra for 3ai and 3aii, 3aiii, 3bi and 3bii and 3biii.
