Intermolecular charge transfer (ICT) enhanced resonance Raman scattering of charge transfer complex is investigated experimentally and theoretically. The evidence for intermolecular charge transfer on resonance electronic transition is visualized with charge difference density. The resonant Raman spectra reveal that the intensity of Raman peaks are strongly enhanced on the order of 104, by comparing with the normal Raman scattering spectrum. ICT complexes can be used in fluorescence-, photoluminescence-, and electrochemistry-based techniques for sensing target molecules. These strong charge-transfer Raman peaks would enable discrimination of important target molecules from interferants that is normal Raman scattering for the isolated target molecules.
