ABSOLUTE INFRARED INTENSITIES OF BINARY-MIXTURES OF LIQUID CHLOROBENZENE AND TOLUENE

Absolute infrared intensities of binary mixtures of liquid chlorobenze ne and toluene were determined from transmission measurements. In gene ral, the integrated intensities between isosbestic points of the <(nu) over tilde>alpha(m) '' spectra were linear with respect to the mole fr action of the pure components. The alpha(m) '' spectra of the pure liq uids were curve-fitted with bands of classical damped harmonic oscilla tor shape. For most fundamentals, the experimental spectra of the mixt ures and synthetic spectra obtained by mixing data from the fitted ban ds of the pure components agreed to within 2-4%. Larger deviations (7- 15%) occurred for some of the bands, indicating molecular interaction between chlorobenzene and toluene.
