Given its ability to detect all iron centers, to identify their electronic structures, and to quantify the ratios of the different iron forms present in a sample, many researchers turn to Mössbauer spectroscopy when wanting to address structural and mechanistic questions involving iron proteins.

It is shown that the structure information for a lattice or periodic pattern can be obtained by measuring the diffracted spectrum of a broadband light source at one spatial position in the far field.

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1992
The spectra of quantized chaotic billiards from the point of view of scattering theory are discussed. It is shown how the spectral and resonance density functions both fluctuate about a common mean. A semiclassical treatment explains this in terms of classical scattering trajectories and periodic orbits of the Poincaré scattering map.

Although providing extensive detail, the time-resolved experiments described here can be quite complex and the instrumentation is not always readily available. However, a number of national fluorescence user facilities funded by the National Institutes of Health or the National Science Foundation are currently in operation and are dedicated to the use ...

Fusion Technology, 2000
Plasma spectroscopy is a diagnostic tool which is most suitable for the measurement of the behaviour of impurity ions, e.g. density, temperature and velocity distributions, also in high temperature plasmas. In most cases accurate knowledge of atomic properties, like emitted wavelengths, transition probabilities and collision cross sections is needed ...

Absorption spectroscopy is one of the most widely used techniques employed for determining the concentrations of absorbing species (chromophores) in solutions. It is a nondestructive technique which biologists and biochemists and now systems biologists use to quantify the cellular components and characteristic parameters of functional molecules.

Science, 1972
Although nonlinear spectroscopy evolved slowly in its initial stages, it is now becoming an important new branch of atomic and molecular spectroscopy. A variety of phenomena are being observed for the first time, either in steady state or in transient behavior.
