Pre-lab preparation
1. Read the text, Shriver, Atkins, Langford, (SAL) pages p. 117 - 125.
2. Practice sketching the symmetry elements, e.g. Figures 2.5 to 2.11. Note that it is often
much simpler to make multiple sketches of projections of the molecule and indicating the
symmetry elements with lines and labels than to attempt perspective drawings, especially
for the more complex shapes.
