- Idealised models usually consist of a simple intermolecular pair potential, whose purpose is often to study underlying physical phenomena.
- Realistic models are usually designed to study a specific atomic or molecular system with a certain degree of realism.
- Force fields consist of, hopefully transferable, parameters for molecular sub-units. They are designed to be applicable to a variety of molecular systems, over a range of conditions.
