Investigation of structural evolution of hydrogen-bond networks of water clusters at 1 and 300 K

Computer simulation of water clusters (H$_2$O)$_n$, Na$^{+}$(H$_2$O)$_n$ and K$^{+}$(H$_2$O)$_n$ (${n\le8}$) at temperatures of 1 and 300 K was carried out using the Monte Carlo method. All the types of the hydrogen-bond network structures at equilibrium configurations of the water clusters and, among them, the most probable ones at temperatures of 1 and 300 K, were detected. The analysis of the most probable types of hydrogen-bond networks at equilibrium configurations of water clusters revealed that clusters with $n$ water molecules inherit the configuration of clusters with ${n-1}$ water molecules with an accuracy of one hydrogen bond.
