This lists the [[character table]]s for the more common [[point groups in three dimensions|molecular point groups]] used in the study of [[molecular symmetry]]. These tables are based on the [[group theory|group-theoretical]] treatment of the [[symmetry]] operations present in common [[molecule]]s, and are useful in molecular [[spectroscopy]] and [[quantum chemistry]].  Information regarding the use of the tables, as well as more extensive lists of them, can be found in the references.<ref>{{cite book | last = Drago | first = Russell S. | title = Physical Methods in Chemistry | publisher = W.B.

Hi there. Let me begin by introducing the writer, her name is Sophia. Doing ballet is some thing she would by no means give up.

== Notation ==
For each non-linear group, the tables give the most standard notation of the finite group isomorphic to the point group, followed by the [[Order (group theory)|order of the group]] (number of invariant symmetry operations). The finite group notation used is: Z<sub>n</sub>: [[cyclic group]] of order ''n'', D<sub>n</sub>: [[dihedral group]] isomorphic to the symmetry group of an ''n''&ndash;sided regular polygon, S<sub>n</sub>: [[symmetric group]] on ''n'' letters, and A<sub>n</sub>: [[alternating group]] on ''n'' letters.
 
The character tables then follow for all groups.  The rows of the character tables correspond to the irreducible representations of the group, with their conventional names in the left margin.  The naming conventions are as follows:
 
* ''A'' and ''B'' are singly degenerate representations, with the former transforming symmetrically around the principal axis of the group, and the latter asymmetrically. ''E'', ''T'', ''G'', ''H'', ... are doubly, triply, quadruply, quintuply, ... degenerate representations.
* ''g'' and ''u'' subscripts denote symmetry and antisymmetry, respectively, with respect to a center of inversion.  Subscripts "1" and "2" denote symmetry and antisymmetry, respectively, with respect to a nonprincipal rotation axis.  Higher numbers denote additional representations with such asymmetry.
* Single prime ( ' ) and double prime ( <nowiki>''</nowiki> ) superscripts denote symmetry and antisymmetry, respectively, with respect to a horizontal mirror plane σ<sub>h</sub>, one perpendicular to the principal rotation axis.
 
All but the two rightmost columns correspond to the [[symmetry operation]]s which are invariant in the group.  In the case of sets of similar operations with the same characters for all representations, they are presented as one column, with the number of such similar operations noted in the heading.
 
The body of the tables contain the characters in the respective irreducible representations for each respective symmetry operation, or set of symmetry operations.
 
The two rightmost columns indicate which irreducible representations describe the symmetry transformations of the three Cartesian coordinates (''x'',&nbsp;''y''&nbsp;and&nbsp;''z''), rotations about those three coordinates (''R<sub>x</sub>'',&nbsp;''R<sub>y</sub>''&nbsp;and&nbsp;''R<sub>z</sub>''), and functions of the quadratic terms of the coordinates(''x''<sup>2</sup>,&nbsp;''y''<sup>2</sup>,&nbsp;''z''<sup>2</sup>,&nbsp;''xy'',&nbsp;''xz'',&nbsp;and&nbsp;''yz'').
 
The symbol ''i'' used in the body of the table denotes the [[imaginary unit]]: ''i''<sup>&nbsp;2</sup>&nbsp;=&nbsp;&minus;1.  Used in a column heading, it denotes the operation of inversion. A superscripted uppercase "C" denotes [[Complex conjugate|complex conjugation]].
 
== Character tables ==
 
=== Nonaxial symmetries ===
These groups are characterized by a lack of a proper rotation axis, noting that a <math>C_1</math> rotation is considered the identity operation.  These groups have [[Involution (mathematics)|involutional]] symmetry: the only nonidentity operation, if any, is its own inverse.
 
In the group <math>C_1</math>, all functions of the Cartesian coordinates and rotations about them transform as the <math>A</math> irreducible representation.

=== Cyclic symmetries ===
The families of groups with these symmetries have only one rotation axis.
 
==== Cyclic groups (''C''<sub>n</sub>) ====
The cyclic groups are denoted by ''C''<sub>n</sub>.  These groups are characterized by an ''n''-fold proper rotation axis ''C''<sub>n</sub>.  The ''C''<sub>1</sub> group is covered in the [[#Nonaxial groups|nonaxial groups]] section.

==== Reflection groups (''C''<sub>nh</sub>) ====
The reflection groups are denoted by  ''C''<sub>nh</sub>.  These groups are characterized by i) an ''n''-fold proper rotation axis ''C''<sub>n</sub>; ii) a mirror plane ''σ<sub>h</sub>'' normal to  ''C''<sub>n</sub>. The ''C''<sub>1''h''</sub> group is the same as the ''C''<sub>s</sub> group in the [[#Nonaxial groups|nonaxial groups]] section.

==== Prismatic groups (''D''<sub>nh</sub>) ====
The prismatic groups are denoted by ''D''<sub>nh</sub>.  These groups are characterized by i) an ''n''-fold proper rotation axis ''C''<sub>n</sub>; ii) ''n'' 2-fold proper rotation axes ''C''<sub>2</sub> normal to ''C''<sub>n</sub>; iii) a mirror plane ''σ<sub>h</sub>'' normal to ''C''<sub>n</sub> and containing the ''C''<sub>2</sub>s.  The ''D''<sub>1''h''</sub> group is the same as the ''C''<sub>2''v''</sub> group in the [[#Pyramidal groups|pyramidal groups]] section.
 
The D<sub>8''h''</sub> table reflects the 2007 discovery of errors in older references.<ref name="ShirtsFixJCE"/> Specifically, symmetry operation column headers 2S<sub>8</sub> and 2S<sub>8</sub><sup>3</sup> were reversed in the older references.

Hi there. Let me begin by introducing the writer, her name is Sophia. Doing ballet is some thing she would by no means give up. Distributing manufacturing is where my main income arrives from and psychic readings online psychic reading (conniecolin.com) it's some thing I truly enjoy. For many years he's been living in Alaska and he doesn't strategy on altering it.
