A structural investigation of the constituents of Athabasca bitumen by proton magnetic resonance spectroscopy

A structural investigation has been made of the constituents of the Athabasca bitumen by proton magnetic resonance spectroscopy. The chemical structures within the bitumen are expressed in terms of carbon-type distribution which is derived from proton distribution, elemental analyses, and molecular weight data. An estimate has been made of the structure of the aromatics within the fractions by determining the peripheral and internal aromatic carbon atoms and relating ratios of peripheral aromatic carbons to total aromatic carbons to those of known fused ring compounds.
