Molecular Symmetry and Group Theory |

The molecule opposite possesses the symmetry elements: E, C_{2}, σ(xz) and σ(yz).
By noting the movement of the dark-coloured H atom, it can be seen that the operation C |

This may be represented by the following equation:

where (by convention) the notation

Complete the following **‘multiplication table’** for this molecule.

Note: The result of any two operations is also a symmetry operation of the molecule. This is a requirement for the operations to form a **mathematical group.**
