摘要：

A double-beam photoacoustic spectrometer has been designed and constructed to permit acquisition of optical, thermal, and dimensional data from a variety of substances including opaque materials. Powders, gels, solids, and liquids may be analyzed directly with a minimum of sample preparation. Some spectra such as that of holmium oxide powder are included to illustrate instrumental operation and the simplified theoretical description. © 1979, American Chemical Society.
