Infinite Symmetry Elements and Crystallographic Space Groups
摘要
Chapter Three extends the discussion to the crystal lattice, which immediately introduces translational symmetry to reflect the periodic nature of crystal structures—considered infinite objects. Accordingly, the topics covered include infinite symmetry elements, which lead to crystallographic space groups, their symbols, visualization, and their description in the International Tables for Crystallography, concluding with a detailed discussion of the equivalent positions within space groups.
