CT interactions and e-mv coupling in BEDT-TTF (ET) salts and complexes

Accurate values of ET+ electron-molecular vibration (e-mv) coupling contants have been obtained through polarized microreflectance spectra of (ET)2[Mo6O19], The information gained allow us to fully analyze the spectra of a different CT complex, (ET)2[Pt(S2C4O2)2]where ET+ dimers are separated by the Pt(II)-dithiosquarate ion. In this case, a partial CT is observed between ET dimers and the anion.
