ABSTRACT
Our laboratory has been involved in the determination of the structures and energetics of small hydrogen-bonded clusters by various quantum chemical methods including semiempirical, density functional, and ab initio Møller-Plesset perturbation theory and coupled cluster methods. Clusters involving formic acid, nitric acid, glycolic acid and water molecules have been studied. The computational challenges encountered, the strategies used to face them, and some of the results obtained are surveyed.
