Several petroleum-derived materials have been structurally characterized in terms of their hypothetical average molecules using a combination of 1 H and 13C n.m.r. spectroscopy. Steps were taken to ensure that reliable 13C n.m.r. data were obtained, including adding a relaxation agent, chromium acet
