Thermodynamic properties of mixtures

The infrared spectra of solid, liquid and gaseous maleic anhydride are reported from 300 to 3200 cm−1, together with the Raman spectra of the liquid. All but two of the fundamentals are assigned in a straightforward manner on the basis of depolarization ratios and gas-phase band contours. The infrared spectra of some solutions in the carbonyl stretching region are also reported and discussed. An electronic mechanism is proposed to explain the large splitting of the two carbonyl frequencies of anhydrides.
