Abstract

FT-IR and FT-Raman studies of ¹³C- and ³⁴S-labeled bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) electron-donor molecules were made, and the results are presented. Assignments for fundamental vibrations in ET were verified. Spectral data suggest that ET has no center of symmetry (confirming X-ray data) and that the data can be reconciled by a <i>D</i>-type point group with only slight interactions occurring between the four molecules per unit cell.
