Chia, Lawrence H. L. published the artcileMolecular polarizability. Conformations of polar substituted ethanes, SDS of cas: 594-81-0, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) (1973), 766-71, database is CAplus.
The mol. distributions of the rotational isomers and the dihedral angles between polar groups of CICH2CCl:CH2 and ten bromo- and chloro-substituted ethane derivatives were estimated from dipole moments and molar Kerr constants determined for CCl4 solutions at infinite dilution at 25°. Polarizations and refractions of these solutions were also determined
