Modulated structures dictionary (msCIF) version 3.2.1

_atom_site_displace_xharm.atom_site_label

Definition:

   

      Modulation parameters are usually looped in separate lists.
      Modulated parameters are the atom positions (displacive
      modulation), the atomic occupation (occupational modulation)
      and/or the anisotropic (or isotropic) ADP.  
      _atom_site_displace_xharm.atom_site_label is the code that identifies 
      an atom or rigid group in a loop in which the x-harmonics components 
      of its displacive modulation are listed. In the case of a rigid group, 
      this list would only include the translational part of its displacive 
      modulation. The rotational part (if any) would appear in a separate list 
      (see _atom_site_rot_xharm.atom_site_label). This code must match the 
      _atom_site.label of the associated coordinate list and conform to the 
      rules described in _atom_site.label.
