✦ Synopsis

Magnetic susceptibility measurements are made at room temperature on heavy petroleum products. They provide characteristic values of the diamagnetism of such organic compounds with high molecular masses. By the use of the Pascal's rules the average number of condensed aromatic rings, in asphaltenes and other heavy petroleum fractions, must be small and undoubtedly less than in the well-known Yen's model.
