Ki. Pokhodnia et al., ASSIGNMENT OF FUNDAMENTAL VIBRATIONS AND ESTIMATION OF ELECTRON-MOLECULAR VIBRATION COUPLING-CONSTANTS FOR BIS(ETHYLENEDIOXY)TETRATHIAFULVALENE (BEDO), Synthetic metals, 56(1), 1993, pp. 2364-2371
The i.r. absorption and Raman spectra of BEDO are investigated. All fu
ndamental vibrations are assigned using correlations between the obtai
ned data and those for a well-known compound BEDT-TTF (ET). Comparativ
e normal coordinate analysis has been done. The results are used for c
alculation of electron-intramolecular vibration coupling constants of
BEDO based superconducting charge-transfer complexes. Comparison of th
ese values with the constants obtained earlier for ET shows that BEDO
is a perspective donor for searching new superconductors on its basis.
