Notes:
13C-cross-polarization/magic angle spinning solid-state NMR spectroscopy is used to investigate the graphitization process of a pyrolyzed formophenolic resin. The formation of a 2-dimensional graphitelike lattice, growing with the duration of the laser pyrolysis, is shown. A one-parameter-condensation model is used to estimate, from our dipolar-dephasing NMR experimental data, the quaternary-to-tertiary aromatic fraction, the number of condensed aromatic rings (from 10 to 23 units), and the average cluster diameter (from 9 to 14 Å).
