Crystallography Flashcards
rotational axis symetry
How many times does the structure repeat itself as you spin around the C axis, most commonly comes as 2,3,4, and 6

Rotational symetry
mirror plane
if you cut the structure along this it will be mirrored on both sides

mirror plane
Inversion Symmetry
when the shape is identical around a plane that passes through multiple axis, frequently accompanied by other types of symmetries.

Crystal systems
describing the crystals based on their symmetry.

C axis
the axis with the maximum amount of symetry, usually represented as up/down

A axis
comes out of the front of the diagram, usualy the shortest
