Modern crystallography has a very interdisciplinary character. Crystallographers have a holistic approach to the studied materials.
A physicist, is probably interested in physical properties of a crystal or a special effect, for the chemist synthesis, reactions
and chemical bonds of molecules are in the focus and the materials scientist studies and models e.g. real structure, microstructure
and properties of materials. From a crystallographers point of view those aspects are all facets of the same object called crystal.
He tries to find a consistent view of correlations between chemical composition, structure and properties of a material.
Crystallography with synchrotron radiation is mostly done in medium to short wave X-ray spectrum at particle energies of E>2keV,
in Germany mainly at HASYLAB at DESY. It requires qualitatively new experiments: use of the adjustability of the primary radiation
(e.g. for energy dispersive powder diffractometry, anomalous dispersion, EXAFS), its collimation (e.g. high resolution, interferometry,
standing waves), its polarisation (non-Bragg-scattering, atomic anisotropies, X-ray crystal optics) and its time structure (kinetics).
These fields of research are developing dynamically.
The availability of powerful, bright synchrotron radiation is a prerequisite for successful structure determination. Its technique
will even be more powerful with the so called X-ray laser (see FEL).

The solid hydrogens (H2, D2, HD) are considered essential for the discovery of new quantum many-body
effects of density. Numerous calculations of exciting properties of dense hydrogen have been made, such as
the recently predicted ‘metal superfluid’ state. However, experimental verification presents technical
challenges and often the observed properties are more subtle than predicted. Determination of the structure of
phase II of deuterium is a clear illustration of the special status of the solid hydrogens.
