centrosymmetric materials

Centrosymmetric materials are substances whose internal structure is symmetric with respect to a central point. This means that if you imagine drawing a straight line through the center and flipping the material around that point, the arrangement of atoms or molecules remains unchanged. Such symmetry influences how the material interacts with light and electric fields, often resulting in properties like the absence of electric polarization in the absence of external influences. In essence, these materials have a balanced, mirror-like symmetry centered at a point, affecting their physical behaviors and responses.
