Spectroscopic order out of spectroscopic chaos

International Journal of Quantum Chemistry, 1987
AbstractA concept is advanced explaining how low resolution studies of chaotic spectral regions can result in assignable regular spectra. The concept draws on ideas from resonance scattering theory, and application is made to interpretation of vibrational spectra in the quasicontinuum.

Beta-Ray Spectroscopes

Review of Scientific Instruments, 1950
This paper is a review of the various types of beta-ray spectrographs and spectrometers. The principal theoretical results as to the resolving power and luminosity attainable under various conditions are briefly related. Finally the construction and performance data of a number of instruments described in the literature are collected, and compared by ...

Spectroscopic Studies of Sulfides

Reviews in Mineralogy and Geochemistry, 2006
Spectroscopic methods are the most direct and powerful means of obtaining experimental information on the electronic structures of materials. They also provide crucial information on aspects of crystal structure, crystal chemistry, solution chemistry and chemical speciation in mineralogical or geochemical systems.

Spectroscopic electron tomography

Ultramicroscopy, 2003
The elemental mapping techniques in analytical transmission electron microscopy (TEM), energy filtered imaging (EFTEM) and EDX-mapping, are shown to provide new routes for tomographic reconstructions of 3D chemical maps on the nanoscale. The inelastic scattering does not only provide chemical sensitivity but also improves the linear projection ...
