The Fundamentals of Infrared Spectroscopy
... L = sample pathlength An absorption band can be characterized by two parameters; the wavelength at which maximum absorption occurs, and the intensity of absorption at this wavelength. In an absorption spectrum, the intensity of the band is proportional to the number of molecules (i.e. the concentrat ...

Gamma spectroscopy
Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, in such as the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced. A detailed analysis of this spectrum is typically used to determine the identity and quantity of gamma emitters present in a gamma source, and is a vital tool in radiometric assay. The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.
