The TIP4PQ/2005 model [1] is a re-parameterisation of the TIP4P/2005 potential for quantum path integral simulations of water, in particular for the ice phases. The difference between the TIP4P/2005 and the TIP4PQ/2005 models is the dipole moment, which increases from 2.305D to 2.38D thanks to the difference in the charges: TIP4P/2005 q(H) (e) is 0.5564 whereas for the TIP4PQ/2005 model this becomes 0.5764e.

Density maximum
The TIP4PQ/2005 model has a density maximum in the liquid phase at 280K [2].
