Molecular polarisability. The conformations of some polynuclear aromatic hydrocarbons
Abstract
Molar Kerr constants are reported for 9-phenylanthracene, 9,10-diphenylanthracene, 9,9′-bianthryl, 1-phenylnaphthalene, and 2-phenylnaphthalene as solutes in non-polar media. Analysis of the experimental data indicates that the preferred solute conformations are defined by dihedral angles Φ(between the aromatic ring planes) of ca. 67°, 67°, 70°, 50°, and 20°, respectively.
