The polarized reflectivity spectra of the single crystals of three organic conductors (ET) 8[ Hg 2X 6(C 6H 5Y)] 2 (X, Y = Cl, Br) have been studied. The electronic IR band with a plasma edge is observed in the spectra similar to most conducting ET compounds. However, a group of the electron-vibrational bands usual for other ET salts is not observed which has been accounted for by the peculiarities of crystal structure due to which the vibrational modes responsible for electron-vibrational interaction belong to non-totally symmetric type.
