Symmetry operators
WebThe symmetry of a molecule is determined by the existence of symmetry operations performed with respect to symmetry elements. A symmetry element is a line, a plane or a point in or through an object, about which a rotation or reflection leaves the object in an orientation indistinguishable from the original. A plane of symmetry is designated by ... Web• Multiplication of symmetry operations is the successive performance of two or more operations to achieve an orientation that could be reached by a single operation e.g., i2 = E; S 4 S4 = S4 2 = C 2; C4σh = S4 etc. • The order in which successive different symmetry operations are performed can affect the result.

WebSep 27, 2024 · The symmetry elements that a molecule may possess are: E - the identity. The identity operation consists of doing nothing, and the corresponding symmetry … In group theory, geometry, representation theory and molecular geometry, a symmetry operation is a geometric transformation of an object that leaves the object looking the same after it has been carried out. For example, as transformations of an object in space, rotations, reflections and inversions are all symmetry operations. Such symmetry operations are performed with respect to symmetry elements (for example, a point, line or plane). In the context of molecular symmetry, a s…
