Hydrogen-Fluoride/Water Mixture

F. Gygi, G. Galli, F. Ree



Equimolar mixture of water and hydrogen fluoride under pressure.

Quantum simulations have shown that both pressure and chemistry weaken H-bonding in the mixture and have identified molecular complexes formed under pressure, including hydronium fluoride. These simulations involved 600 atoms and the optimization Of 5*10^8 degrees of freedom at each MD step (1 ps ~ 15,000 steps). They were possible on the Lab ASCI machines, using a highly optimized version of the JEEP code.
