nonorthorhombic

Nonorthorhombic refers to crystal systems that do not possess orthorhombic symmetry. The orthorhombic crystal system is characterized by three mutually perpendicular axes of unequal length. Therefore, any crystal system that deviates from this specific arrangement of axes and their lengths would be considered nonorthorhombic. This includes other crystal systems such as cubic, tetragonal, hexagonal, monoclinic, and triclinic. Each of these systems has distinct requirements for the angles between crystallographic axes and the relative lengths of these axes. For example, the cubic system has four equal axes at 90-degree angles, while the monoclinic system has three unequal axes with two at 90 degrees and one at a different angle. The classification of a crystal into a particular system, including whether it is orthorhombic or nonorthorhombic, is determined by its diffraction pattern, physical properties, and geometric arrangement of atoms or molecules. Understanding the crystal system is crucial in materials science, mineralogy, and solid-state physics as it dictates many of the material's properties, including its optical, mechanical, and electrical behavior.
