This section contains documents created from scanned original files, which are inaccessible to screen reader software. A "#" symbol is used to denote such documents.
Readings are mix of Professor Wuensch's original handouts and other published materials, presented here in the order used in class. The individual original handouts are also published here as compiled notes.
Several readings are from the books:

The Monoclinic Space Groups. pp. 76-101 In [TABLES_52].
This reading illustrates how the three-dimensional space groups are systematically derived by adding each of the point groups in a particular crystal system -- and with pure rotation replaced by a screw axis and/or a mirror plane by a glide plane -- to each of the space lattices that are able to accomodate them.
