Abstract
Raman spectra of crystals of TTF-TCNQ as well as of powdered samples of TTF, TCNQ and (TTF)7I5 are reported for the temperature range from 4 to 77K. An assignment of the observed lines in TTF-TCNQ to the intramolecular lines in TTF and TCNQ is given. By comparing the frequency shift of Raman lines between neutral and charged TTF and TCNQ and the corresponding lines in TTF-TCNQ a charge transfer of roughly 0.5 electrons in TTF-TCNQ is obtained. In the low frequency range five out of six lattice modes are found and assigned to their symmetry species.Keywords
