WebCrystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles … WebAug 2, 2010 · This can also be used to calculate experimental tilt angle between two poles. This is very useful script for crystallographers. In this script only four out of seven crystal system and few very well known materials has been included, but one can easily extend this to for many other materials and the remaining three crystal systems.
