A. Tadjeddine et A. Le Rille, Adsorption of cyanide on gold single crystal investigated by in situ visible-infrared difference frequency generation, ELECTR ACT, 45(4-5), 1999, pp. 601-609
The adsorption of CN- on gold single crystal has been monitored by visible-
infrared difference frequency generation (DFG). We show a significant effec
t of the surface orientation on the adsorption strength of CN-, which decre
ases from (110) to (100) and (111). Both the linewidth and the potential tu
ning rate of the DFG resonances do not depend on the electrode surface orie
ntation, indicating that CN- is tightly and linearly bound to its nearest s
urface gold atom. (C) 1999 Elsevier Science Ltd. All rights reserved.
