abstract = {Networks are increasingly recognized as important building
blocks of various systems in nature and society. Water is
known to possess an extended hydrogen bond network, in which
the individual bonds are broken in the sub-picosecond range
and still the network structure remains intact. We
investigated and compared the topological properties of
liquid water and methanol at various temperatures using
concepts derived within the framework of graph and network
theory (neighbour number and cycle size distribution, the
distribution of local cyclic and local bonding coefficients,
Laplacian spectra of the network, inverse participation
ratio distribution of the eigenvalues and average
localization distribution of a node) and compared them to
small world and Erdos–Re + ́nyi random networks. Various
characteristic properties (e.g. the local cyclic and bonding
coefficients) of the network in liquid water could be repro-
duced by small world and/or Erdos–Re + ́nyi networks, but
the ring size distribution of water is unique and none of
the studied graph models could describe it. Using the
inverse participation ratio of the Laplacian eigenvectors we
characterized the network inhomogeneities found in water and
showed that similar phenomena can be observed in Erdos–Re
+ ́nyi and small world graphs. We demonstrated that the
topological properties of the hydrogen bond network found in
liquid water systematically change with the temperature and
that increasing temperature leads to a broader ring size
distribution. We applied the studied topological indices to
the network of water molecules with four hydrogen bonds, and
showed that at low temperature (250 K) these molecules form
a percolated or nearly-percolated net- work, while at
ambient or high temperatures only small clusters of
four-hydrogen bonded water molecules exist.},
