WEB TUTORIAL - Group Theory

Basic Principles

Using group theory you can predict the number of IR and Raman active bands you will expect to see from a given sample if you know its geometry.

You will need to be familiar with the following tools to utilse Group Theory:

• Symmetry Elements

A Recap: What are they? What they represent in a molecule?
• The Flow Diagram

How to use the flow diagram.
• Point Group Character Tables

What each part represents.
• The Reduction Formula

How it works? What to Expect.

 

If you are confident with the above topics, why not try an example?
