Summary In this paper we present a vibrational-spectroscopy technique which combines the advantages of coherent anti-Stokes Raman spectroscopy (CARS) and linear Raman difference spectroscopy. The method which we call CARS difference spectroscopy can be applied for the study of small frequency shifts and/or bandwidth changes in the CARS spectra of liquid mixtures and solutions. First we develop the theory necessary for the interpretation of experimental data obtained from CARS difference measurements of mixtures of two Raman-active liquids and present some model calculations for benzene-toluene mixtures of different concentrations. Then the experimental arrangement used for CARS difference measurements as well as some examples of recorded spectra are described. We show that it is possible to observe the effects of dilution on CARS spectra with high accuracy by applying the discussed technique.
