Abstract
The occurrence of substantial (two-threefold) transfer of infrared ban d intensity between juxtaposed coadsorbates having widely separated (2 00-250 cm(-1)) oscillator frequencies is demonstrated directly for int ermixed NO/CO adlayers on ordered Ir(111) and (110) electrodes by sele ctively removing CO or NO by electrochemical oxidation and reduction, respectively. The surprisingly large effect is nevertheless semiquanti tatively consistent with the predictions of theoretical dipole-couplin g models. (C) 1998 American Institute of Physics.
