Infrxed spectrv of TTF-TCAQ in inert gzs matrices and in thin fiLms deposited below room temperature shk the presence of TTF" and TCNQO. Lmmwities such as TTF" and TCNQ' in thin films and other forms of TTF-TCNQ may account for the variation in the condu&ity measurements reported thus far.
The linear coupling constants desLrlbing the interaction of the one-electron molecular orbitals with the molecular vlbrations in TCNQ are caiculatcd using a semiempirlcal spectroscopically parametcrtzcd CNDO molecular orbital model. The cartcsian displacements for the normal mode of vibrations are c
The S(2p) binding energies have been measured at room temperature in TTF-TCNQ and related compounds. The results indicate an electron transfer of 1 .O % 0.5 electrons/molecule for TTF-TCNQ.
