From: Defluorination and adsorption of tetrafluoroethylene (TFE) on TiO2(110) and Cr2O3(0001)

Charge density distributions for TFE adsorbed (dissociated) as C2F3 and F on TiO2(110) (left panel) and on Cr2O3(0001) (right panel). A higher accumulation of charge about the C2F3 C=C observed on Cr2O3(0001).
