Module overview
This module builds on the student’s core understanding of the structure
of atoms and molecules to predict their behaviour using state-of-the art
computational chemistry methods. This will involve learning how
quantum chemistry methods can be used to study atoms and molecules
and how classical mechanics methods can be used to simulate molecules
and biomolecules. These two methodologies are related and we will
explore their respective and mutual applications. Emphasis will be placed
upon learning how to use these methods for real-life applications.
