Low temperature polarized reflectance spectra of β-(BEDT-TTF)2PF6
Source abstract
Abstract
We measured the polarized reflectance and Raman spectra of β-(BEDT-TTF) 2 PF 6 from 360 K down to 5 K. Both the IR and Raman spectra show the drastic changes below 280 K at which the metal-insulator transition occurs. On lowering the temperature, the Raman band at 1470 cm -1 shows a split suggesting the charge disproportionation (CD) among BEDT-TTF molecules.
