Structure of supercooled water in clusters and bulk and its relation to the two-state picture of water: Results from the TIP4P-ice model

Mostrar todas las versiones(2)

The structure of water clusters (H 2O) n (n = 40-200) and bulk water were examined by molecular dynamics simulations using the TIP4P-ice water model. The analysis of the low-temperature structures in terms of the local structure index (LSI) showed a bimodal distribution. This finding supports the tw...
