Abstract:

A new phenomenon of enhanced IR absorption has been revealed recently and reported in the present paper. In referring to the surface enhanced IR absorption (SEIRS)^[l], which is limited to systems of particular molecules (PNBA, etc.) adsorbed on island films of Au, Ag metals, the newly discovered phenomenon is of significant importance in fundamental studies as well as in applications of electrocatalysis and surface analysis, since nanostructured transition metals or alloys were involved in this phenomenon.
