This module is divided into two related components: Symmetry and Group Theory and Vibrational Spectroscopy. The Group Theory component of the course discusses aspects relating to symmetry of molecules, assigning Point Groups, assigning a Basis Set, and deriving Irreducible Representations. Additionally, this first component explores how Group Theory can be applied to the construction of molecular orbital diagrams for simple molecules and vibrational spectroscopy (IR and Raman). The latter leads into the second component of the course, which deals with Vibrational spectroscopy [IR and Raman] in more detail. The workshop component of the module reinforces aspects of the lecture course, and for the Group Theory segment a computer-based package is available to support the lecture material.

By the end of the module the student should be able to:

• Demonstrate an understanding of the terms used when discussing symmetry, and appreciate the difference between symmetry elements and symmetry operations;
• Apply their knowledge of symmetry to assign point groups to molecules;
• Determine a suitable basis set, and derive irreducible representations;
• Apply Group Theory approaches to molecular vibrations and molecular bonding;
• Demonstrate an understanding of the underlying principles associated with vibrational spectroscopy.
