WebFigure 12.6.6: The General Features of the Seven Basic Unit Cells. The lengths of the edges of the unit cells are indicated by a, b, and c, and the angles are defined as follows: α, the angle between b and c; β, the angle between a and c; and γ, the angle between a and b. Cubic: a = b=c, alpha= beta=gamma = 90 degrees. Webdescribes the symmetry of the diffraction pattern. The Laue symmetry can be lower than the metric symmetry of the unit cell, but never higher. That means: A monoclinic crystal with β= 90° is still monoclinic. ... Patterson map is the same as that of the crystal structure. The Patterson function has some very interesting features: It consists ...
