X-ray Raman scattering

Resonant x-ray spectra and dangling bond density Hexagonal boron nitride Resonant x-ray emission or resonance x-ray Raman scattering has recently been often studied using synchrotron radiation facilities. A successful example of the application of the DV-ATa method to the x-ray spectra is this resonance x-ray emission spectra of hexagonal boron nitride (A-BN). 

Details on other complementary techniques, such as small and wide angle X-ray scattering, X-ray Raman scattering, and X-ray emission, and synchrotron infrared spectromicroscopy methods are not discussed here. However, these methods can provide complementary information on the macromolecular structure and functional group chemistry of organic molecules at different resolution in different sample environments. 

Freund has proposed a new, nonlinear X-ray diffraction method to determine the valence electron charge density in a wide variety of covalently bonded materials. The technique is based on the spontaneous parametric down conversion of a source of X rays interacting with a suitably oriented crystal and involve measurements comparable in difficulty with X-ray Raman scattering.

Almost every modem spectroscopic approach can be used to study matter at high pressures. Early experiments include NMR [ ], ESR [ ] vibrational infrared [33] and Raman [ ] electronic absorption, reflection and emission [23, 24 and 25, 70] x-ray absorption [Tf] and scattering [72], Mossbauer [73] and gems analysis of products recovered from high-pressure photochemical reactions [74]. The literature contains too many studies to do justice to these fields by describing particular examples in detail, and only some general mles, appropriate to many situations, are given. 

A number of reviews have appeared covering the various aspects of borate glasses. The stmcture, physical properties, thermochemistry, reactions, phase equihbria, and electrical properties of alkah borate melts and glasses have been presented (73). The apphcation of x-ray diffraction, nmr, Raman scattering, in spectroscopy, and esr to stmctural analysis is available (26). Phase-equihbrium diagrams for a large number of anhydrous borate systems are included in a compilation (145), and thermochemical data on the anhydrous alkah metal borates have been compiled (17). 

The methods used to characterise polymers are partly familiar ones like X-ray diffraction, Raman spectroscopy and electron microscopy, partly less familiar but widespread ones like neutron scattering and nuclear magnetic resonance, and partly... 

Barkla, originally interested mainly in v-ray scattering, discovered characteristic x-rays by an experimental method similar in principle to that described above. His experimental arrangement (Figure 1-7) is reminiscent of that used today in studies of the Raman effect. By using an absorber in the form of sheets (Figure 1-7) to analyze the scattered beam in the manner of Figure 1-4, he obtained results that clarified the earlier experiments described above.
