Therefore, the character table contains multi-membered classes and degenerate irreducible representations. a. Table A.5. 4. multiplication table, thus the character table can be re‐written to describe a reducible representationof the group, v v ’ m • m is described as a reducible representation of the C 2v point group as it can be broken down to a simplerform or reduced. This implies that the point group corresponds to a constructible polygon which can be used for tiling the plane. Of course, this is a simplification which nevertheless reflects the dominant character of this orbital. Assign symmetry labels (labels of irreducible representations) for the group orbitals shown in Figure 13.27. b. A simple example for a D5h symmetric molecule is the cyclopentadienyl anion $ \text{E} \,{\text{(1)}} $ $ C_5 \,{\text{(2)}} $ $ C_5^2{} \,{\text{(2)}} $ $ C_2 \,{\text{(5)}} $ $ \sigma_h \,{\text{(1)}} $ $ S_5 \,{\text{(2)}} $ Character and product tables for d5h point group.
