Asphaltene samples obtained from bitumen processed at three Indian refineries were characterized for chemical composition and structure by nuclear magnetic resonance (n.m.r.) spectroscopy and X-ray diffractometry (XRD). The average structural parameters were obtained by combined 1H, 13C and DEPT spe
A "S NMR spectrum has been obtained from an asphaltene sample for the first time. Asphaltene from the Athabasca tar sands bitumen, Alberta, Canada, was oxidized with Ru""', which selectively converts sulphide sulphur into the corresponding sulphone. The "S NMR spectrum of this sample at 30.7MHz feat
