The crystals were pulverized and diluted in pressed pellets of KBr. Results in the spectral range around 2900 cm-1 taken at room temperature are presented. The spectra clearly reveal absorption lines varying in position and intensity between the different species in a characteristic manner.eninfo:eu-repo/semantics/openAccessTetrathiafulvalen , Organischer Supraleiter , FT-IR-Spektroskopie530Detection of CH2 stretch vibrations in α-, αt- and β-(BEDT-TTF)2I3 by FT-IR absorption spectroscopyarticle
