The Reflection Spectra of the New Organic Conductor (BEDT-TTF)4Hg3Cl8

Abstract

Polarised reflectivity spectra at room temperature in the region 200 to 25000 cm−1 are investigated for quasi-two-dimensional conductor (ET)4Hg3Cl8 single crystals. The optical properties of this compound are almost isotropic in the plane parallel to conducting layers. In the reflection spectra, the electronic band with metal-like edge and the electron-vibrational bands are observed. The spectra are satisfactorily described by the phase phonon model including electron damping and the dependence of molecular vibrational frequencies on the molecular charge. [Russian Text Ignored].
