Learning objectives for this unit are to:
- Know the number of expected vibrational modes in a molecule containing "N" atoms
- Generate reducible representations using a degrees of freedom basis set or a simple bond stretching basis set
- Decompose reducible representations within a point group into their irreducible components using the great orthogonality theorem
- Assign the irreducible representations to translations, rotations and vibrations
- Determine which vibrational modes are IR active and Raman active
- Use Mulliken symbols to predict the molecular deformations that correspond to a particular vibrational mode
- Apply the selection rules for IR and Raman active modes to experimental scenarios
