of water can be described reasonably well by simple model intermolecular
potentials with site charges and a Lennard-Jones centre. By modifying the
potential parameters one can make families of liquids with weaker hydrogen
bonds, with altered network structures or isotropic molecules with the same
2-body correlations. Teresa Head-Gordon, Pablo Debenedetti and I have been
studying properties of these liquids in order to determine the importance of
hydrogen-bond strength, network structure etc. We find some surprises - for
example hydrophobic solutes are more soluble in water than in liquids with
weaker hydrogen bonds and the dielectric constants increase as the geometry of
the network structure is changed.<o:p></o:p></FONT></SPAN></SPAN></P>
