With the complex use of the methods of dipole moments, the Kerr effect, the Cotton-Mouton effect, and molecular mechanics, it was shown that the 2-halogenated ethylbenzenes studied in solutions of CCl/sub 4/ are an equilibrium mixture of approximately equally populated trans and gauche rotamers on the C-C bond. In both conformations, the plane of the aromatic ring is close to shielding of the C-H bond.
