The signal waveform observed in optoacoustic measurements is complex and highly
dependent on sample for open-cavity cells and pulsed optical excitation. A Helmholtz …

An efficient and low-cost spectroscopic tool, photoacoustic spectroscopy (PAS), is described.
Although this tool is suitable for all levels of chemistry and physics laboratories, it is …

Pulsed laser photoacoustic spectroscopy has been used as the basis for sensing analytes in
aqueous systems. The spectra obtained with the photoacoustic system are significantly …

The use of Impulse response measurements for signal re-covery In photoacoustic
spectroscopy Is described. The technique Is compared with the use of sequential single …

Photoacoustic spectroscopy (PAS)*, the technique of 'listening'to the optical absorption by
molecules, involves the illumination of a material by light (in the UV-visible--near-IR region) …

Time-resolved laser optoacoustic method was developed for the measurement of the spatial
distribution of laser fluence rate in uniformly absorbing and scattering condensed turbid …

Diffuse light scattering is shown, for some well-known examples such as powdered rare-
earth oxides and semiconductors, to be a conditio sine qua non for obtaining any …

We discuss the application of photoacoustic methods to vibrational spectroscopy on liquid
and solid specimens. Based on tunable CO 2 lasers as radiation sources, examples are …

A simplemodification of a photoacoustic spectrometer to allow for the direct generation of
first-and second-order dif-ferential spectra Is described. Uncorrected spectra are presented …
