'''Idealised models''' usually consist of a simple [[Intermolecular pair potential|intermolecular pair potential]], whose purpose is often to study underlying physical phenomena, such as generalised [[phase diagrams]] and the study of [[phase transitions]]. It is entirely possible that a number of the models bear little or no resemblance to real molecular fluids.

See also: [[force fields]].
'''Realistic models''' are usually variants of idealised models, parametrised to study a specific atomic or molecular system with a certain degree of realism. These models are usually designed to reproduce a subset of experimental physical properties, thus a certain model may be more suitable to a particular study, whist being wholly inadequate in the study of a distinct question.

'''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 thermodynamic conditions.
