Jump to: navigation, search

The TIP4Q model [1] is a re-parameterisation of the original TIP4P potential for simulations of water. TIP4Q is a rigid planar model, having a similar geometry to that of the Bernal and Fowler model.

Parameters[edit]

The TIP4Q model consists of a Lennard-Jones site for the oxygen atom, and three charge sites (data from Table I).
