Abstract
We present the optical conductivity, infrared- and Raman-active charge sensitive phonon modes of the new 7,7′,8,8′-tetracyanoquinodimethane (TCNQ) anion radical salt containing N-methyl-2,5-dimethyl-pirazinium cations (N-Me-2,5-(Me)2-Pz)+. Comparison of the calculated frequencies of the totally symmetric TCNQ modes with corresponding vibrations in the (N-Me-2,5-(Me)2-Pz)(TCNQ)2 salt is given. An attribution of the main bands observed in the spectra of the salt is offered and discussed. The charges estimation with both, structural and spectroscopic methods is in good agreement with each other and confirms almost full charge transfer from cation to TCNQ species.
