Modulated and composite structures dictionary (msCIF) version 1.0.1

Category CELL_WAVE_VECTORS

Name:
'_cell_wave_vectors_[ms]'

Definition:

   Data items in the CELL_WAVE_VECTORS category record details
   about the set of independent modulation wave vectors q~i~ and
   their measurement. The diffraction vectors are indexed in
   the form ha*+kb*+lc*+sum~i~ (m~i~q~i~). sum~i~ is taken
   over all wave vectors. In this version of the dictionary, the
   index i has been restricted to be less than 9.

Example:

Example 1 - example corresponding to the one-dimensional incommensurately modulated structure of K~2~SeO~4~.
