Abstract
The crystal structures and phonon frequencies of alpha- and beta- phases of (BEDT-TTF)(2)I-3 salts are computed by the Quasi Harmonic Lattice Dynamics (QHLD) method. Experimental specific heat data of the beta- phase can be r eproduced only by introducing also low frequency intra-molecular vibrations . The strength of the electron-phonon (e-ph) coupling is evaluated.
