Abstract
Inelastic electron tunneling spectra of thin films of bis(ethylenedith io)tetrathiafulvalene (BEDT-TTF) and its salts: a low temperature supe rconductor K-(BEDT-TTF)2Cu(NCS)2 and an insulator (BEDT-TTF)2Mo6O19 ar e measured at 4.2 K in the range 230-1650 cm-1 and compared with infra red spectra of the same compounds at room temperature. The obtained vi brational bands are assigned following theoretical normal mode calcula tions. Electron-molecular vibration coupling theory of charge-transfer organic compounds is extended to the case of electron tunneling spect ra.
