WebApply each of the symmetry operations of the point group (E, C2(z), etc.) to the molecule, and determine how many atoms are not moved by the operation. Then, multiply this number by the so-called character contribution of that symmetry operation. This will yeild a series of h numbers, where h is the number of distinct symmetry operations in WebTranscribed image text: V) A portion of the character table for D2h is shown below, but is missing the identification of the effects of symmetry operations on translation along the x, y, and z-axes in the point group D2h.
