CHEM 107 Lecture Notes - Lecture 2: Ethane, Buckminsterfullerene, Diborane
Document Summary
Lecture 02 - symmetry and point groups (ch. Compete set of symmetry operations that describe given molecuels or objects. 1: all molecules fall into a variety of pt. groups. 2: want to understand how we can assign pt. groups to diff. molecules based on their symmetry operations that they posses. What about other axis perpendicular to c3 principle axis. Remember: pt. groups are either going to have 0 or n c2 axis. We generate equivalent con gurations the molecules unchanged, except for our imaginary labels. [remember that these labels are imaginary they are there to help us and book keep and tell what"s going on when we do our operation] Is there a h? no! remember, the horizontal mirror plane is the one to the principle axis. Remember you take coordinates x, y, z and change them to -x, -y, -z. We can only have 0 or 1 inversion.
