    • At negative pressures, smaller systems may not reproduce cavitation events that we observe in larger systems. Thus it is important that we consider the large 8000 molecule systems for (Formula presented) [F.W. Starr, Ph.D. thesis, Boston University (1999)]. We also simulated one system of 64 000 molecules, but did not observe any significant differences in structure or cavitation events. We typically simulate each state point using eight processors in parallel. We obtain simulation speeds of approximately (Formula presented) per particle per update. The total simulation time is about 1000 CPU days

    • The SPC/E model treats water as a rigid molecule consisting of three point charges located at the atomic centers of the oxygen and hydrogen which have an OH distance of 1.0 Å and a HOH angle of (Formula presented), the tetrahedral angle. Each hydrogen carries a charge (Formula presented) and the oxygen carries a charge (Formula presented) where e is the magnitude of the electron charge. In addition, the oxygen atoms of separate molecules interact via a Lennard-Jones potential with parameters (Formula presented) and (Formula presented)

    • Substitution of deuterium for hydrogen is expected to have little effect on the individual RDFs. Isotopic substitution is reflected by the weighting factors. To compare with experimental measurements of 4, we use weighting factors for (Formula presented), given by (Formula presented), and (Formula presented)

    • We obtain state points at (Formula presented) and (Formula presented) and (Formula presented) by quenching a configuration of the supercooled liquid state points at (Formula presented). The configurations analyzed at (Formula presented) are not equilibrated, as the required simulation time far exceeds the computational resources available; rather, they correspond to a glassy state quenched from the supercooled liquid. We consider these state points to be glassy since previous simulations indicate that SPC/E approaches a glass for (Formula presented) 2334
