FT-IR absorption spectra of polycrystalline pressed sample soft he Organic metals and superconductorsa alpha-beta-(BEDT-TTF)2I3 and(BEDT-TTF)2Cu(NCS)2

IR absorption spectra of polycrystalline pressed samples of the organic metals a-(BEDT-TTF)2I3, /?-(BEDT-TTF)2I3 and (BEDT-TTF)2Cu(NCS)2 are presented and discussed. Normal protonated as well as deuterated materials were studied. The spectra range from 400 cm"1 to 5000 cm"1 and are similar to the IR reflectance spectra reported ealier. The data are of special interest in view of the fact that recently bulk superconductivity was observed in such polycrystalline samples of organic metals, and therefore the application of organic superconductors for the preparation of electronic devices seems possible
