Abstract

Low-temperature studies of organic and inorganic compounds was suggested by Rosencwaig in 1980 as one new area in the future trends of photoacoustics and photoacoustic spectroscopy. At cryogenic temperatures, optical absorption spectra often exhibit much sharper and less complex features than the corresponding room-temperature spectra. The use of piezoelectric detection for high-resolution, laser-induced optoacoustic spectroscopy at cryogenic temperatures was first reported by Shaw and Howell in 1981. A ceramic disc piezoelectric transducer was compressed in a copper clamp along with a fused quartz substrate on which the sample was applied. Spectra of cubic neodymium sesquioxide, Nd<sub>2</sub>O<sub>3</sub>, cooled to less than 10 K, in the yellow spectral region (16 400 to 17 400 cm<sup>−1</sup>) exhibited sharp lines of full width at half maximum 10 cm<sup>−1</sup>. Such spectral sharpening, and simplification, upon cooling the sample enhance selectivity for analysis of mixtures.
