Abstract:

A discussion of absorption phenomena in the infrared 2.5 to 15 micrometers spectra region is presented. Mechanisms surveyed include the attenuation of electromagnetic waves by dielectrics and metals molecular absorption processes, lattice vibrations in bulk and powdered dielectrics, band gap, free carrier and multiple phonon absorption in semiconductors absorption in bulk and powdered metals and absorption by polymeric one-dimensional conductors. Also presented is a review of quantitative methods of determining the optical constants of solids, liquids and gases and their possible sources of error. The results of quantitative absorption measurements on tri-n-butyl phosphate, polymethylmethacrylate, cellulose, polyvinyl alcohol, and ureaformaldehyde are included. Author
