Abstract

A brief summary of very recently published works on vibrational spectroscopic studies of adsorbed molecules (a) on metal single crystals or evaporated films with low surface area and (b) on supported metal catalysts or metal oxide catalysts with large surface area is presented here. So far as (a) is concerned some new results of EELS, reflection-absorption IR spectroscopy and IR emission spectroscopy (with cooled monochromator or interferometer) are discussed. With regards to topic (b) absorption by the support materials (SiO2, Al2O3, MgO, TiO2, etc.) usually prevents access to the region below about 1200 cm-1. Therefore we concentrate mainly on the methods (diffuse reflection, photoacoustic or emission spectroscopy) offering vibrational data in a wide frequency range. Some new developments in emission and FIR spectroscopy in our laboratory are discussed.
