PPT-SYMMETRY AND GROUP THEORY

DrKoshy John Department of chemistry Symmetry Elements The elements used to ascertain the symmetry of a molecule quantitatively is called Symmetry elements A symmetry element is a geometrical entity such as a line about which a rotation is carried out a point about which an inversion is carried out or a plane about which a reflection is carried out to generate an equivalent orientation or indistinguishable orientation.
