Effective Potentials

Density functional theory with dispersion-correcting effective potentials is used to examine the low-lying isomers of the formic acid hexamer. The lowest-energy structure is a chairlike ring of six Z monomers. π-Stacked structures consisting of a dimer and tetramer lie higher in energy.
