Molecular structure

molecular structure is called the geometrical, spatial relative arrangement of the atoms in a molecule.

Usually cartesian coordinates (x, y, z) are used, in order to indicate the positions of the atoms, or also internal coordinates, D. h. Connection lengths and connection angles and if necessary. The the angle.

Experimentally the molecular structure can be determined by means of crystal analysis.

For small molecules from few atoms the structure can be computed also with the methods of theoretical chemistry.

The molecular structure determines considerably important characteristics such as dipole moment and symmetry (z. B. Group of points after Schönflies).
