Abstract : The infrared spectra of butyl pyridinium chloride/aluminum chloride and 1-methyl 3-ethyl imadazolium chloride/aluminum chloride room temperature molten salts have been examined over a range of mole ratios (acidities). Bands observed in the 4000-630/cm range have been assigned and spectral changes attributed to the formation of ion pairs, which may involve distortion of the aromatic ring since there is an accompanying loss of aromatic character. This effect is more pronounced in the imidazolium melts where more highly basic melts can be studied due to the greater liquidus range. Several isobestic points are reported.
