Note that each column and each row has each symmetry operation
represented only once. _‘_————'___—_————_—_—_____ Example 12.4 The multiplication table of the representation is the same as
that of the group Show that the representation given in equation 12.16 has the same multiplication table as
the operations in the group sz (Table 12.2).
From the multiplication table of the R’s of equation 12.16: RUE) R(C2) RM) ROTQ) R(E) 1 —1 1 1

Table 12.2 by the R’s of equation 12.10, we see that they are identical. ——————————__—_____________ Table 12.4 Character Table for the C2v Group Cgv E C2 0'V (xz) 03’, (yz) A1 1 1 1 1 z, zz, x2, y2
