WebThese models are parameterized in terms of the O3-O3-O3 angle and the model oxygen radius. M2 is allowed to distort. Crystallographic parameters such as interatomic distances, unit cell volume, and packing distortion are determined as a function of the O3-O3-O3 angle. WebApr 24, 2024 · The ground state partial model is considered an immutable component of the crystal, with a status similar to common restraints (for example, geometry or non-crystallographic symmetry), as in ...
