Abstract
AgTCNQ has been prepared, and studied by infrared and Raman spectroscopies. The various preparation techniques were found to lead to the same Ag+TCNQ− composition. The Raman spectra show strong resonance enhancement of the totally symmetric modes. Differences in the degree of coupling of these modes with the electronic transitions were observed. The infrared spectra also show the presence of the totally symmetric modes, which become infrared active through the electron-phonon coupling mechanism.
