Infrared photoacoustic spectroscopy - Advantages and disadvantages in surface science and catalysis research

Abstract
Optical spectroscopy techniques in the area of infrared (IR) region, including IR photoacoustic spectroscopy (PAS), always played an important role in the characterization of surfaces and interfaces, as they permits the investigations of surface species, as well as direct monitoring of phenomenon of the reaction and/or process occurred. Our concem in this paper is to present selected examples of scientific works in area of surface science where one of the spectral technique applied was Fourier transform infrared photoacoustic spectroscopy (FT-IR/PAS).
