The chemical shifts of the ring protons in a series of monosubstituted mesitylenes and durenes, and of the 10-protons of a series of 9-substituted triptycenes and anthracenes have been measured in dimethyl sulfoxide, acetone, 2-methoxyethanol, and carbon tetrachloride. The solvent dependence of the substituent chemical shifts has been analyzed by linear free energy relations. The systems all show similar dependence which increases with increasing dielectric constant of the solvent. This does not result from the field effect being transmitted through the medium, but appears to arise from the formation of a hydrogen-bonded interaction between the solvent and the hydrogen of the solute. The substituent chemical shifts appear to arise from contributions from substituent field, resonance, magnetic anisotropy, and solvent effects.

Dielectric constant and density measurements of solutions of chloro-, bromo-, and iodo-benzene together with those of p-dichloro-, p-dibromo- and p-diiodo-benzene in carbon tetrachloride at 25� are given. Distortion and atomic polarization values for the polar solutes are estimated by a method proposed by B�ttcher; the values are compared with other estimates of PD and PA. To obtain quantitative information of atomic polarizations, using B�ttcher's method, greater precision than is usual in solution dielectric constant measurements would be required.
