Definition. A Cayley table is a multiplication table for a finite group. You'll sometimes hear them called group multiplication tables. The Cayley table for a group G helps you with computation: you can easily look up group products and even the inverses of elements.

C2v H2O Water Other examples of the C2v point group include: trisilane (Si3H8), furan, thiophene, pyridine, nitrobenzene, formaldehyde (methanal), thioformaldehyde, cyclopropene, propane, diazomethane and cyanamide.

The C2v Point Group This point group contains four symmetry operations: E the identity operation. C2 a twofold symmetry axis. σv the first mirror plane (xz) σv' the second mirror plane (yz)

Character table for point group C3v C3vEcubic functionsA1+1z3, x(x2-3y2), z(x2+y2)A2+1y(3x2-y2)E+2(xz2, yz2) [xyz, z(x2-y2)] [x(x2+y2), y(x2+y2)]

Example: the point group C3v is isomorphous to S3 = {E, (1 2 3), (1 3 2), (1 2), (1 3), (2 3)}, which means that there is a one to one correspondence between the two sets of operations.

The character table is a square matrix where the columns are indexed by conjugacy classes and the rows are indexed by representations. If the structure of the group is clearly understood, then the columns can easily be specified, which means that we know the number of rows as well as the number of columns.

Point Group of NH3 The symmetry elements of NH3 are E, 2C3, and 3 sigma-v. To elaborate, the molecule is of C3v symmetry with a C3 principal axis of rotation and 3 vertical planes of symmetry. The image of the ammonia molecule (NH3) is depicted in Figure 1.8.

The NH3 molecule is trigonal pyramidal and its point group is C3v. The z axis is collinear with the principal axis, the C3 axis.
