Coordinates of Symmetry Elements and Space Groups
It is intended that the following course will give you a good understanding of the effects of symmetry elements and the use of different coordinate systems. This course is crucial to really understanding crystallography and symmetry.
- Understanding Coordinate Systems
- Effects of two-fold rotation axes (Orthorhombic)
- Effects of mirror planes (Orthorhombic)
- Effects of inversion centres (Orthorhombic)
- Effects of screw axes and glide planes (Orthorhombic)
- Effects of centring (Orthorhombic)
- Symmetry elements to space groups and vice versa (Orthorhombic)
- Derivation of unknown symmetry elements (Orthorhombic)
- Test your coordinate knowledge (Orthorhombic)
- Isomorphic Space Groups
- Other coordinate systems (Hexagonal, Monoclinic)
- Effects of higher rotation axes
- Effects of roto-inversion
- Understanding space group symbols of other crystal systems
- Wyckoff positions
- Supergroups and subgroups
