Structural chemistry
The structural chemistry is a branch of chemistry that deals with spatial structures in molecules and solids .
One of the main tasks is to derive general rules on how the chemical and physical properties of the constituents determine the resulting structures (for example, the relationship between the electron configuration of the crystal building blocks and the symmetry of the resulting crystal lattice). Another field of activity is the formulation of general laws for structure-property relationships.
For the structure elucidation serve diffraction methods, including crystallographic methods ( X-ray diffraction , electron diffraction , neutron diffraction ) and the diffraction of gases (electron diffraction), and methods of molecule (particularly microwave spectroscopy) and solid state spectroscopy . A distinction must be made between methods that can only reproduce the link between atoms (constitution) and those that produce three-dimensional structural information (bond lengths, angles, torsion angles, atomic coordinates).
