Water dimer is the archetype for aqueous hydrogen bonding,and investigations on it generally focused on the global minimum on the potential energy surface(PES),but the rest stationary structures were ignored.In this paper,10 stationary structures on the PES were obtained by the counterpoise corrected optimization at MP2/aug-cc-pVDZ level.The properties of these structures,such as binding energy and dipole moment,etc.were also calculated.Results show that the most stable structure is #1 with Cs symmetry and ...
