Character Tables of Symmetry Group and Symmetry Group Elements


"Every molecule has a point group associated with it, which are assigned by a set for rules (explained by Group theory). The character tables takes the point group and represents all of the symmetry that the molecule has."

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
E (Mulliken Symbol)(doubly degenerate or two dimensional)
T (Mulliken Symbol)(thirdly degenerate or three dimensional )
Subscript 1symmetric with respect to the Cnprinciple axis, if no perpendicular axis, then it is with respect to σv
Subscript 2anti-symmetric with respect to the Cnprinciple axis, if no perpendicular axis, then it is with respect to σv
Subscript gsymmetric with respect to the inverse
subscript u
anti-symmetric with respect to the inverse
primesymmetric with respect to σh (reflection in horizontal plane) 
double primeanti-symmetric with respect to σh ( opposite reflection in horizontal plane)

                                        also watch symmetry operations:
