The hydration state of HO−(aq)

The hydration state of HO(aq)

The HO(aq) ion participates in myriad aqueous phase chemical processes of biological and chemical interest. A molecularly valid description of its hydration state, currently poorly understood, is a natural prerequisite to modeling chemical transformations involving HO(aq). Here it is shown that the statistical mechanical quasichemical theory of solutions predicts that HO · [H2O]3 − is the domin...

Modeling of the hydration shell of Adenine

The molecular geometry of complex of adenine with 8 water molecules was calculated with Hartree-Fock (HF). The standard 6-31G(d) basis set has been employed. The existence of C-H…O Hydrogen bonds between the water molecules and the hydrophobic part of nucleobase is stablished. We optimized structures and computed interaction energies of all complexes of adenine with water molecules step by step...

Oxidation–hydration weathering of uraninite: the current state-of-knowledge

Oxidation–hydration weathering of uraninite, the most common U-bearing mineral in nature, comprises various physical and chemical processes that lead to the destruction of the fluorite-type structure of uraninite where U is present as tetravalent. This results in replacement of uraninite by weathering products containing U in hexavalent form, i.e. as uranyl ion, UO2 2+. The final assemblage of ...
