Photoacoustic X-Ray Absorption Spectroscopy
1988When materials are irradiated by X-rays, several effects occur, e. g. absorption, scattering, fluorescence, and electron release, as seen in Fig. 1. Heat generation should also be observed on absorption of electromagnetic waves even for the X-ray absorption process.

Photoacoustic spectroscopy for process analysis
Analytical and Bioanalytical Chemistry, 2005Photoacoustic spectroscopy (PAS) is based on the absorption of electromagnetic radiation by analyte molecules. The absorbed energy is measured by detecting pressure fluctuations in the form of sound waves or shock pulses. In contrast to conventional absorption spectroscopy (such as UV/Vis spectroscopy), PAS allows the determination of absorption ...
