What is group explain about construction of character tables?
In group theory, a branch of abstract algebra, a character table is a two-dimensional table whose rows correspond to irreducible representations, and whose columns correspond to conjugacy classes of group elements.
How do you create a character table in group theory?
The various sections of the table are as follows:
- The first element in the table gives the name of the point group, usually in both Schoenflies (C3v) and Hermann-Mauguin (3m) notation.
- Along the first row are the symmetry operations of the group, E, 2C3 and 3σv, followed by the order of the group.

What is the purpose of the character table?
A character table summarizes the behavior of all of the possible irreducible representations of a group under each of the symmetry operations of the group.
What is A and B in character table?
Symbols under the first column of the character tables. A (Mulliken Symbol) (singly degenerate or one dimensional) symmetric with respect to rotation of the principle axis. B (Mulliken Symbol) (singly degenerate or one dimensional) anti-symmetric with respect to rotation of the principle axis.
What is character table in point group?
A character table is a 2 dimensional chart associated with a point group that contains the irreducible representations of each point group along with their corresponding matrix characters.
How do I find the character table in a group?
The character table is a square matrix where the columns are indexed by conjugacy classes and the rows are indexed by representations. If the structure of the group is clearly understood, then the columns can easily be specified, which means that we know the number of rows as well as the number of columns.
