摘要：
Fourier transform infrared absorption spectra of structurally different phases of the radical cation salt (BEDT-TTF)2I3 in the range of the molecular vibrations of the donor are presented. The low-temperature spectra provide exact fingerprints of the different phases as long they have different unit cells. Additional differences concerning the positions of ethylene groups reflect themselves in the CH2-stretching vibrations. As a result, it could be shown that the ethylene groups of the alpha(t)-phase and beta-phase must have a different order. Concerning the tempering of the different phases, it is shown that at least alpha(t)- and x(t)-(BEDT-TTF)2I3 are the same.
