In bankruptcy 1, after an overview of a few ancient elements of using symmetry in chemistry is given, the scene is determined by way of introducing a few team theoretical concepts which were hired via chemists. bankruptcy 2 considers intimately the character and the different types of teams which were hired through chemists and others of their description of chemical structures. In bankruptcy three a relatively new mathematical formalism is gifted that's now being more and more used for the translation of stereochemical phenomena. The symmetry of molecules is analyzed from a group-theoretical standpoint in bankruptcy four, whereas in bankruptcy five the symmetry of the chemical graphs which are conventional to symbolize either natural and inorganic molecules is addressed. Chapters four and five jointly surround purposes equivalent to the enumeration of many alternative chemical isomers and research of the symmetry features of various lately synthesized molecules similar to the fullerenes.

3. The identity characters are also the degeneracies of the functions which transform as those representations. 50 Chemical Group Theory 4. The sum of the squares of the dimensions of the irreducible represen­ tations give the order of the group. 5. The regular representation of a group is a reducible representation that has the order of the group as the character under the identity opera­ tion, (1N), and zeros for all of the other characters. The regular repre­ sentation reduces to a sum of all the irreducible representations of the group, each multiplied by its dimension.
