Neutron crystallography

An interesting example is the interaction of benzene with C mim][PF6, which has been investigated by crystallography, neutron scattering and computational studies. 

The structures of many simple hydrazinium salts have been determined using single-crystal X-ray crystallography. Neutron diffraction studies have shown that, besides normal hydrogen bonds, bifurcated and probably trifurcated bonds are also common in some of the hydrazinium salts. Table 1.4 lists some of the compounds along with their crystal data and N-N bond distances [6,19].

Laboratory, particularly to study ferrimagnetic materials. In 1994, a Nobel Prize in physics was (belatedly) awarded for this work, which is mentioned again in the next chapter, in Section 7.3. A range of achievements in neutron crystallography are reviewed by Willis (1998). 

X-ray, neutron, and electron diffraction techniques are used to determine crystal structures and can thus be used for molecular structure determinations. Because of its high resolution and applicability to small and often weakly diffracting samples, x-ray crystallography and powder diffraction are by far the methods of choice for most structure determinations on crystalline compounds,...

The mechanism by which serine peptidases, particularly serine endopep-tidases (EC 3.4.21), hydrolyze peptide bonds in peptides and proteins has been extensively investigated by X-ray crystallography, site-directed mutagenesis, detection of intermediates, chemical modification, H-NMR spectroscopy, and neutron diffraction [2-14], These studies revealed that all serine peptidases possess a catalytic triad, composed of a serine, a histidine, and an aspartate residue, and a so-called oxyanion hole formed by backbone NH groups.
