CH2 vibrations in radical cation salts based on the donor BEDT-TTF

Abstract

Investigations of the CH2 stretch vibrations in radical cation salts based on the donor BEDT-TTF and the neutral donor itself are presented. The spectra taken by Fourier transform infrared absorption technique not only demonstrate the importance of the relationship between the possible positions of the CH2 groups in the BEDT-TIF molecule and the physical properties of the organic metal but also offer the opportunity to achieve structural information by the use of a simple method.
