Реферат:	eng: Vanadyl metal-organic complexes (VO2+) in genetically different fractions of natural oils and bitumens are studied using EPR. Phenolic vanadyl complexes are identified having an isotropic spectrum with the parameters A (o) = 8.82 mT, g (o) = 1.996, as opposed to the previously studied axially symmetric spectra of vanadyl porphyrin complexes with A (o) = 9.46 mT, g (o) = 1.976 (A (aEuro-) = 16.79 mT, A (aSyen) = 5.78 mT, g (aEuro-) = 1.964, g (aSyen) = 1.983). The simultaneous presence of both types of vanadyl complexes in the samples under consideration results in a complex spectrum, which is identified by computer simulation using the ESR1 software.
