โœฆ Synopsis

Abstract

The empirical potential EPEN/2 has been used to establish the structures of isolated hydrogenโ€bonding ammonia clusters. The most stable forms of the dimer have a linear or nearโ€linear structure. The trimer has a closed structure with zero dipole moment. Two stable tetramer forms were found: one with a closed structure and zero dipole moment in agreement with experimental findings, and one with a pyramidal structure with nonzero dipole moment which may be an artifact of the EPEN/2 potential. The relation of the dimer structures to the limited available experimental information is discussed.
