Optical rotation of petroleums
Journal of the American Oil Chemists' Society, 1967AbstractAlthough oils and oil distillates are usually dextrorotatory, some levorotations can be measured in lower boiling distillates. Fractional distillation of a Colombia crude oil of Eocene age showed that optical rotation is maximal at an average molecular weight of 464.

Symmetry Rules for Optical Rotation
The Journal of Chemical Physics, 1966It is shown that to produce optical rotation in a chromophore, a potential function must have the symmetry properties of a pseudoscalar in the symmetry group of the unperturbed chromophore. It is thus possible to establish regional rules of optical rotation without recourse to particular models and assumptions of the electronic states of the ...
