Abstract

Infrared absorptions of solutions of eight acids in benzene have been examined over the 3500 cm-1 region. Quantities Q, defined as (area under a "free" O-H bond) + (weight fraction of solute present), can be extrapolated to zero concentration, giving Q, for each acid, much more certainly than can the dielectric polarizations published for the same systems by Pohl et al.1-3 The quotients Q/Q0 appear rectilinearly related to partial molar polarizations over major portions of the entire concentration range; using this observation, new estimates are made of polarizations and dipole moments for the acid monomers concerned.
