Molecular Polarizability of Organic Compounds and Their Complexes:XLIX.~1 Molar Volumes of Polyaryl Systems in Solutions,Extrapolated to Infinite Dilution,Their Additivity,and Steric Structure of the Molecules

摘要

Molar volumes of a number of polyaryls and of several model systems at infinite dilution in carbon tetrachloride and benzene were determined.The molar volumes of the compounds under study are additive by bonds,groups,and molecular fragments.The dipole moments and Kerr molar constants of the compounds under study can be found by a simplified additive method.As follows from the additive analysis of the molar volumes of diphenyl,para-substituted diphenyls,heteroaromatic analogs,and a number of polyaryls,the molecules of these compounds are acoplanar in the solutions,and the degree of their acoplanarity is the same as in diphenyl.
