Summary
Table A.1 shows the symmetry operations of the point groups more commonly used in the book. The notation for the symmetry operations is the following:
E identity transformation
Cn proper rotation of 2π/n radians (n ∈ ℕ): the axis for which n is greatest is termed the principal axis
Sn improper rotation of 2π/n radians (n ∈ ℕ): improper rotations are regular rotations followed by a reflection in the plane perpendicular to the axis of rotation
i inversion operator (equivalent to S2)
σ mirror plane
σh horizontal reflection plane: perpendicular to the principal rotation axis
σv vertical reflection plane: contains the principal rotation axis
σd diagonal or dihedral reflection plane: bisects two C2 axes
