We present the temperature evolution of polarised Raman and IR reflectivity spectra of TetrathiafulvaleneChloranil (TTFCA) in t he lattice phonon region (10200 cm -1). Quasi Harmonic Lattice Dynamics (QHLD) calculations prove to be essential in discussing the assignment of the phonons and their evolution across the temperature induced neutralionic phase transition.

Abstract
We present the temperature evolution of polarised Raman and IR reflectivity spectra of TetrathiafulvaleneChloranil (TTFCA) in t he lattice phonon region (10200 cm -1). Quasi Harmonic Lattice Dynamics (QHLD) calculations prove to be essential in discussing the assignment of the phonons and their evolution across the temperature induced neutralionic phase transition.File in questo prodotto:
