Investigation of Solids and Surfaces by Photoacoustic Spectroscopy

Solid State and Structural Chemistry Unit, Indian Institute of Science, Bangalore-560 012 After presenting the essentials of the principles and instrumentation involved in photoacoustic spectroscopy, a variety of studies of solids and surfaces carried out by this technique are reported. Some of the important aspects of the spectroscopy examined are signal saturation, intensity enhancement and fluorescence quenching. Applications to the study of amorphous solids, phase transitions and surfaces are discussed
