The result was " a direct consequence of classical interference of different frequency components of an anomalous dispersion region ."

Anomalous dispersion occurs, for instance, where the wavelength of the light is close to an absorption resonance of the medium.
13.
However, atomic scattering factors have imaginary parts due to the anomalous dispersion effect, and Friedel's law is broken by this effect.
14.
This is called " normal dispersion ", in contrast to " anomalous dispersion ", where the refractive index increases with wavelength.

In X-ray crystallography, incorporation of one or more selenium atoms in place of sulfur helps with multiple-wavelength anomalous dispersion and single wavelength anomalous dispersion phasing.

17.
The principal technical advances were in taking absorption spectra in polarized light and measuring dispersion, including the anomalous dispersion near the absorption lines, at low temperatures.
18.
Whereas, if the index increases with increasing wavelength ( which is typically the case for X-rays ), the medium is said to have " anomalous dispersion ".
19.
If the pulse is of sufficient intensity, the spectral broadening process of SPM can balance with the temporal compression due to anomalous dispersion and reach an equilibrium state.

In 1951 Johannes Martin Bijvoet for the first time used in X-ray crystallography the effect of anomalous dispersion, which is now referred to as resonant scattering, to determine absolute configuration.
