关 键 词：control of band-shape from adsorption to anti-adsorption In situ FTIRS studies of CO adsorption on nanostructured surfaces 

摘      要：Molecules adsorbed on nanometer scale metal films exhibit several infrared phenomena, i.e,surface enhanced infrared absorption (SEIRA) [1], Fano-type line shape [2], Abnormalinfrared effects (AIREs) [3]. SEIRA and AIREs are both characterized by enhanced infraredbands of adsorbates except that the direction of AIREs band is inverted to anti-absorption incomparison with that of SEIRA, While Fano-type line shape is known for the bipolar andasymmetric band-shape.
