Complexes of N-Heterobases and Carbonic Acids in Non-Aqueous Media. Structural Investigations by FTIR Spectroscopy and Factor AnalysisA series of FTIR spectra of different concentration ratios of dichloroacetic acid and i-chinoline was investigated by factor analysis. The best results were obtained for difference spectra, in which the dominating bands of the main constituents have been eliminated prior to factor analysis.The component spectra, computed by factor analysis, showed a band of a strong OH…N complex. No evidence was found for O…HN species, i.e., proton transfer does not occur in the investigated system. The formation of complexes of higher order or of dichloroacetic acid dimers has not been ovserved.
