Cellekantlengdene

Cellekantlengdene refers to the lengths of the edges of a unit cell in a crystal lattice. The unit cell is the smallest repeating unit of a crystal structure, and its dimensions and angles define the overall symmetry and properties of the crystal. In three-dimensional crystallography, the unit cell is typically described by three edge lengths, denoted as a, b, and c, and three interaxial angles, denoted as alpha, beta, and gamma. The term "cellekantlengdene" specifically refers to these linear dimensions a, b, and c.

These lengths are fundamental parameters used to characterize and classify crystal structures according to various crystal systems, such as cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, and rhombohedral. For instance, in a cubic system, all three cell edge lengths are equal (a = b = c), whereas in a triclinic system, they can all be different (a ≠ b ≠ c). The precise values of the cellekantlengdene, along with the interaxial angles, determine the volume of the unit cell and are crucial for understanding diffraction patterns, physical properties like density and mechanical strength, and the arrangement of atoms within the crystal. They are typically determined experimentally using techniques such as X-ray diffraction.
