Abstract

The infrared (IR) and Raman (R) spectra of TTF-TCNQ, TTF-TCNQ-15N4, TTF-2H4-TCNQ, and TTF-TCNQ-2H4 have been measured, with particular emphasis on the CN stretching vibrations. The lines at 2206 cm-1 (IR) and 2214 cm-1 (R) are assigned to modes of A1g symmetry. The isotope shift of the IR lines are unusual. The data suggest strong coupling between the CN stretching vibrations and the electronic motions.
