Abstract
Abstract Infrared absorption spectra of salts derived from a new giant analogue of TTF (D) with small inorganic anions have been measured vs temperature. Spectra of the neutral donor (D) and compounds used in its building were studied also. A comparative analysis was used for assignment of the fundamental vibrations of D and its cation-radical salts. Shape of the spectra, i.e. linewidthes and intensities of selected bands, appearance of CT bands above 4000 cm−1 etc., suggest a 1:1 stoichiometry of the salts. T-dependencies of intensities of some bands of DClO4 and DCu(SCN)2 show anomalies which reveal the presence of phase transitions. Observed anomalies are preliminary explained.
