Torsional lattice vibrations in molecular crystals: I. Displacement coordinates and redundancies

Suitable forms of coordinates for torsional lattice vibrations are discussed. It is shown that infinitesimal rotation coordinates may be used if their 'hidden' redundant character is allowed for. Examples of the form of typical torsional force constants are given.
