Notizen:
Polarised infrared reflectivity spectra of some ET-based conducting salts of alpha-type structure are measured and compared: (ET)2I3 (I), (ET)2TIHg(XCN)4 (X=S, Se) (II) and (ET)8[Hg4Br12(CH3C6H4CI)2] (III). For both I and II the electronic reflectivity is greater for the polarisation perpendicular to ET stacks. However, a resolved electron vibrational band in the region of 1 100-1 400 cm-1 is observed for II in the polarisation characterized by lower electronic reflectivity in contrast with the spectra of I. Another difference between I and II is the absence of the pronounced plasma edge in the region of 4 000 cm-1 in the spectra of II, which may be due to high electron damping. For III the electronic reflectivity is low and no resolved electron vibrational band in the region of 1 100-1 400 cm-1 is observed. The peculiarities of the electron-vibrational spectra of I, II and III may be due to the details of the crystal structure. © 1997 John Wiley & Sons, Ltd.
