H and 13C n.m.r. spectra of asphaltenes separated from a heavy crude oil using n-pentane at different temperatures were measured. Average molecular parameters and hypothetical structural models for these asphaltenes were proposed using n.m.r. measurements, calculated molecular weight of unit sheets
## Abstract Glass capillary gas chromatography/mass spectrometry is used to profile Alaskan crude oil for purposes of origin verification. Alaskan oil, sampled at Valdez, Alaska, and transshipped to the U.S. East Coast, is compared with 21 samples of foreign crude oil using GC/MS techniques in whic
