The molar Kerr constant (35 x 10-12) and dipole moment (2.29 D) of 1,3-dichloroacetone in carbon tetrachloride are shown to be compatible with an equilibrium mixture of planar cis/non-planar gauche (6) and non-planar gauche/non-planar gauche (8) conformers with the latter predominating.

Intramolecular Rotation

The magnitudes of dipole moment and molar Kerr constant of 1,2-dichloroethane as solute in carbon tetrachloride, previously recorded by Aroney, Izsak, and Le F�vre, are discussed in relation to internal rotation in the molecule. The results are found to be consistent with a mixture consisting of 31.3% of gauche-isomer and 68.7 % of trans-isomer. Estimation of the potential energy barriers restricting intramolecular rotation is attempted and the results found to be satisfactory.

Measurements of the infinite-dilution dipole moment, molar Kerr constant and molar Cotton-Mouton constant of 1,4-dithiin dissolved in cyclohexane and carbon tetrachloride at 25�C are reported and analysed to provide information concerning the solution-state conformation, the polarizability anisotropy and the magnetic anisotropy of this molecule.

Self Association

Abstract Analysis of infrared hydroxyl multimer absorbances of dilute solutions of cholesterol in carbon tetrachloride as a function of the monomer absorbance strongly favours the interpretation of the association of this alcohol with a monomer-dimer-tetramer model up to a molar fraction of 0.012. This model also explains very well the concentration dependence of the apparent dipole moment. Equilibrium constants and dielectric parameters have been determined. Suggestions about the structure of the various associates are made.

Reported Data

The dipole moments of the ethylene derivatives acrylonitrile, chloroacrylonitrile, methyl vinyl ketone, vinyl bromide, 1,1-dichloroethylene, and tribromoethylene were determined in benzene solution at 20 °C. The measured dipole moments were corrected for the solvent effect by the method of Looyenga. In addition the applicability of the Looyenga equation for the solvent effect was tested on earlier reported data for 20 different molecules, whose dipole moments were derived from dilute benzene and carbon tetrachloride solutions, respectively. The corrected dipole moment values were compared with earlier corrected values calculated according to the method of Le Fevre and Le Fevre and with reported gas values. It was found that for most compounds both methods of correction yielded dipole moment values which differed by 0–10% from the gas values.

The configuration of mercury(II) chloride as a solute in benzene has been investigated through measurements of dielectric absorption, apparent molar weight (490�100), and specific Kerr constant [(2.3�0.3) x 10-12]. Tentative values for the polarizability semi-axes of the mercury-chlorine bond are deduced from the infrared stretching frequency of mercury(II) chloride. The experimental results are consistent with the presence of a non-polar dimeric solute species, or with an equilibrium mixture involving several polymeric forms.
