Modulated structures dictionary (msCIF) version 3.2.1
Category ATOM_SITE_DISPLACE_FOURIER
Name:'ATOM_SITE_DISPLACE_FOURIER'
Parent category:
MS_GROUP
Definition:
Data items in the ATOM_SITE_DISPLACE_FOURIER category record
details about the Fourier components of the displacive modulation
of an atom site in a modulated structure. In the case of rigid
groups, items in this category would only include the
translational part of the modulation. The rotational part would
appear in a separate list of items belonging to the
ATOM_SITE_ROT_FOURIER category. The (in general complex)
coefficients of each Fourier component belong to the child category
ATOM_SITE_DISPLACE_FOURIER_PARAM and may be listed separately.
Category is of type Loop
Category key:_atom_site_displace_Fourier.id
