Abstract
By a combined experimental and computational approach we evaluate the stren gth of electron-phonon coupling in organic superconductors based on the bis -ethylendithio-tetrathiafulvalene (BEDT-TTF or ET) molecule. We consider el ectron coupling to both intra- and inter-molecular phonons. In the case of beta-(ET)(2)I-3 superconductor, the strength of the two types of coupling t urns out to be of the same order of magnitude. (C) 2000 Elsevier Science S. A. All rights reserved.
