celleparametre
Celleparametre, or cell parameters, are the geometric values that define the size and shape of a crystal’s unit cell. They consist of three edge lengths, a, b, and c, and the three interaxial angles, alpha, beta, and gamma, between those edges. Together, these six quantities establish the basic framework of the crystal lattice and set the cell’s volume and overall geometry.
The edge lengths are typically expressed in angstroms, while the angles are given in degrees. The particular
The unit cell volume can be calculated from the parameters using a general formula that involves a,
Determination of cell parameters is a primary outcome of crystallographic experiments, commonly X-ray, neutron, or electron
