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. Complete the character table by determining the irreducible representations that correspond to the translation along the x, y, and z-axes. WebA symmetry element can be a point, axis, or plane. A symmetry operation is the movement of a body (molecule) such that after the movement the molecule appears the same as before. What is c1 point group?
