Abstract
Parameters of nuclear magnetic spin-spin relaxation were determined for oil samples in a wide density range (rho = 770-900 kg/m(3)) by pulsed NMR with a YaMR 08RS relaxometer. Dependences of the relaxation time on the viscosi ty were plotted. An exchange between proton groups with different molecular mobilities was revealed. The self-diffusion coefficients for protons were determined. A molecular dynamic model of oil structure was suggested based on the obtained experimental data.
