摘要：

Charge transfer has been evaluated in stage-2 CxCrFy and CxRhFy GIC's by optical measurements. Charge transfer coefficients f = 0.50 and f = 0.59 per intercalated species have been determined from reflectivity data using the Blinowski-Rigaux model. The corresponding contractions of in-plane C-C bond lengths (δC-C = 4×10-3 A ̊ and 3.3×10-3 A ̊2 respectively) have been deduced. The shift of the E2g mode observed in the Raman spectra has also been correlated to increasing strengths of the in-plane C-C bonds. © 1990.
