Frequencies of maxima of the vibrational component and the component with perpendicular polarization of methyl ethyl ketone (MEK) in C=O vibration band are different by DELTA nu = 6,7 cm^-1. In mixtures with heptane, pyridine, and dimethylsulfoxide (DMSO), there is a decrease in this frequency difference with changing a concentration. However, a feature of the decrease in DELTA nu is different: in mixtures with heptane, both bands are displaced to the high-frequency side, and the vibrational component is displaced faster; in mixtures with pyridine, the components are displaced to the opposite directions. In mixtures with DMSO, the perpendicular component is displaced to the direction of the vibrational component. The peculiarity of the concentration dependence of DELTA nu behavior in mixtures of MEK with chloroform can be explained by possible intermolecular aggregations.
