The TIP4P/2005 model is a re-parameterisation of the original TIP4P potential for simulations of water. TIP4P/2005 is a rigid planar model, having a similar geometry to the Bernal and Fowler (BF) model.
Parameters
(Å) | HOH , deg | (Å) | (K) | q(O) (e) | q(H) (e) | q(M) (e) | (Å) |
0.9572 | 104.52 | 3.1589 | 93.2 | 0 | 0.5564 | -2q(H) | 0.1546 |
Surface tension
The surface tension has also been studied for the TIP4P/2005 model (Ref. 3).
Self-diffusion coefficient
The TIP4P/2005 potential has a self-diffusion coefficient, in bulk water at 298 K, of 0.21 Å2 ps−1 in a classical simulation of 216 water molecules (Ref. 4) (experimental value: 0.23 Å2 ps−1).
