The molar Kerr constants of diazoaminobenzene and its 4,4'-dimethyl, 4,4'-clichloro, 4,4'-dibromo, and 4-nitro derivatives at infinite dilution in benzene at 25� are recorded. No abnormalities in the molar Kerr constant-concentration curves due to dimeric association can be found with any of the above solutes.

Measurements are reported of the infinite-dilution dipole moments and molar Kerr constants of dimethyl sulfone and of the four aryl methyl sulfones p-XC6H4S(02)CH3 (X = H, Cl, Br or NO2) dissolved in carbon tetrachloride or dioxan at 298 K and under light of 589 nm. The experimental data are analysed to obtain information on the solution-state conformations in relation to steric and electromeric effects operative between the aryl and methanesulfonyl groups.

Analysis of the experimental infinite-dilution molar Kerr constants of five p-substituted benzaldehydes (X-C6H4-CHO; X = NO2, CN, F, Cl, Br) as solutes in carbon tetrachloride at 298 K confirms that uniplanar molecular conformations are preferred.

The electric birefringences displayed by the above two liquids have been measured photometrically at wavelengths between 375 and 625 mμ, and Kerr constants Bλ computed relatively to benzene, for which B589 is 0.410 x 10-7 at 25�. Empirical equations connecting Bλ values and refractive indexes with X are developed, and compared in applicability with others from the literature. Data necessary for the determination of molar Kerr constants of coloured solutes in the named solvents are also recorded.

Le Fbre and Solomons recorded the Kerr constants Bγ of carbon tetrachloride and benzene over the wavelength range 375-625 nm to make possible the use of these solvents in examining the anisotropic polarizabilities of coloured solutes. Since, however, unsuspected hydrogen bondings may occur between π-electrons of benzene and protons from a dissolved molecule, and/or because of the various risks of chemical changes when basic substances are studied in carbon tetrachloride, an additional and more inert medium became desirable. Cyclohexane seemed to be the least reactive of the liquids which are available in quantity and easily purified, but no information on the variation of its B constant with wavelength was in the literature; the present measurements were therefore made to fill this gap.

Triatomic Molecules

Measurements of the infinite-dilution molar Kerr constant, field-gradient birefringence constant and Cotton-Mouton constant of carbon diselenide as a solute in carbon tetrachloride at 298 K are reported. From an analysis of the observations, the molecular quadrupole moment, Θ, and the magnetic anisotropy, ΔX, emerge as (+15.4 � 2.7) × 10-40 Cm2 and (-19.6 � 2.6) × 10-5 J T-2 mol-1, respectively. Trends in these and related electric and magnetic properties are considered for the sequence of six linear triatomic molecules of formula XCY (X,Y = O,S,Se).
