Abstract

A rooted digraph is regarded as a protonated water (PW) cluster, and a hydrogen bond (H-B) matrix can represent a rooted digraph. All possible topology-distinct patterns corresponding to PW clusters containing up to 8 water molecules were enumerated by using H-B matrices. We apply the Hamiltonian algorithm combined with ab initio molecular orbital calculations to the optimization of molecular structures for PW clusters up to hexamers.
