In this exercise, symmetry operations can be examined
for a particular molecule.

Sometimes a reorientation of the molecule is needed for a better view of the operation (or due to the way that Chime performs rotations for example). In that cases the following sequence will be shown:

reorientation-delay- **symmetry operation** -delay-back to original orientation

An example: a C_{2} for BF_{3}: (push the square button)

A complex symmetry operation, like a improper axes of rotation, will be seen as a continuous movement, without any delays.

A BF_{3} like molecule: in this exercise, after viewing the symmetry operations, you could try to construct the multiplication table for the rotational sub-group of D_{3h} by performing the products of the symmetry operations. Turn the labels on to follow the atoms. Use the **RESET** button, on the bottom frame, to re-start any operation from the starting configuration.

Do not try to follow atoms labeling them in operations that involve reflections around a symmetry element (planes of symmetry, improper axes of rotation or inversion), since these operations are "shown" by coloring atoms and not actually "performed" as in the case of rotations.

C_{2}H_{6} staggered : in the rotations one of the hydrogens is colored at the beginning of the operation to
highlite the process.

octahedron : a general ML_{6} molecule is shown. No attempt is made to cover all symmetry operations (The S_{2,4} are collinear with the C_{2,4} and the planes are straightforward). Examples of the C^{'}_{2} and C_{3}
are included.
