New Features
• The 2009 release of ICDD databases boasts an
impressive array of new features. This
presentation will demonstrate many of these
new features using DDView+ 2009 and
DDView 2009, ICDD’s own data-mining
software.

Structural Formula: Displays the formula exhibiting the number of atoms of each element
in a molecule and the linkage between atoms or groups of atoms.
Empirical Formula: Displays the chemical formula showing the number of atoms of each
element present in the compound.

New preference: Show all Space Group Symmetry Operators*
This list is generated by expanding the coordinate triplets of the general position
(used as symmetry operators for a complete crystal cell display) by incorporating
the centering elements for non-primitive systems.

• User-selectable Thermal Displacement
Parameter Type*
*PDF-4 only
Ring Patterns*
•
Every entry in the PDF-4+ 2009 database now has a graphical ring pattern. This ring pattern
provides a 2-dimensional simulation of the X-ray pattern for a given phase as it would appear on
a flat 2-dimensional detector such as photographic film, phosphor image plates, or solid state
arrays. The simulation assumes no preferred orientation in the specimen, uniaxial positioning of
the detector (transmission geometry with incident beam centered) and an infinite number of
randomly oriented crystallites. The user is allowed to specify the X-ray wavelength, the sampleto-detector distance, the detector dimensions, and the average crystallite size for the specimen.
