Category GEOM_ANGLE

Name:
'GEOM_ANGLE'

Parent category:
MS_GROUP

Definition:

   

      Data items in the GEOM_ANGLE category record
      details about the bond angles, as calculated from the
      ATOM, CELL and SYMMETRY data. These extensions
      to the core CIF dictionary definitions record the maximum,
      minimum and average values of angles and extend the
      symmetry-operation code used in angle listings to the
      higher-dimensional superspace form. Many GEOM_ANGLE
      datanames are redefined due to the consequent change
      in the way that they are calculated, even if the
      calculation method is not explicit in either this
      dictionary or the core.

Category is of type Loop
