WebThe symmetry of a given molecule depends which type and how many operations leave it unchanged. Before we go over the symmetry of molecules we will discuss all the operations and their mathematical forms (handout on symmetry operations, matrices). In general, an operation can be thought of as a black box that moves or does something to an object WebThe five symmetry elements have associated with them five types of symmetry operation, which leave the geometry of the molecule indistinguishable from the starting geometry.They are sometimes distinguished from symmetry elements by a caret or circumflex.Thus, Ĉ n is the rotation of a molecule around an axis and Ê is the identity operation.
