Vibrational studies of (sup 13)C- and (sup 34)S-labelled bis(ethylenedithio)tetrathiafulvalene (ET) donor molecule

摘要

FT-IR and FT-Raman studies of (sup 13)C- and (sup 34)S-labelled bis(ethylenedithio)-tetrathiafulvalene (BEDT-TTF or ET) electron-donor molecules were made and the results presented herein. Assignments for fundamental vibrations in ET were verified. Spectral data confirms that ET has no center-of-symmetry, and that the data can be reconciled by a D-type point group with only slight interactions occurring between the 4 molecules per unit cell.
