A Point Group Character Tables Appendix A contains Point Group Character (Tables A.1-A.34)to be used throughout the chapters of this book.Pedagogic material to assist the reader in the use of these character tables can be found in Chap.3.The Schoenflies symmetry (Sect.3.9)and Hermann-Mauguin notations (Sect.3.10)for the point groups are also discussed in Chap.3. Some of the more novel listings in this appendix are the groups with five- fold symmetry C5,Csh,Csv,D5;D5d,Dsh,I,Ih.The cubic point group On in Table A.31 lists basis functions for all the irreducible representations of Oh and uses the standard solid state physics notation for the irreducible representations.
