Dielectric absorption and molecular dynamics of formyl-, carboxyl-, and 1,1′-dichloro-ferrocene

Abstract

Dielectric spectra of formyl-, carboxyl-, and 1,1′-dichloro-ferrocene have been examined in benzene in the frequency range of 100 MHz-26 GHz, at various temperatures. In these conditions only one clear dielectric absorption band has been observed and a Debye-type behaviour has been found. Calculation of the macroscopic dielectric relaxation times and the thermodynamic parameters has also been performed. All evidence seems to suggest a type of mechanism for dielectric relaxation, even if at the present stage of research it might be prudent not to indicate a definitive model for the molecular dynamics itself of these compounds.
