WebN2 - For understanding the major- and minor-groove hydration patterns of DNAs and RNAs, it is important to understand the local solvation of individual nucleobases at the molecular level. We have investigated the 2-aminopurine 3H2O monohydrate by two-color resonant two-photon ionization and UV/UV hole-burning spectroscopies, which reveal two isomers, … WebThe internally hydrogen-bonded conformer is predominant also for 2X-phenol species, as calculated on the basis of relative CBS internal free energies and IEF-PCM and FEP/MC solvation free energies. Use of a trihydrate supermolecule model for 2F-ethanol conformers leads to the prediction of the aqueous-solution composition in contrast to the experiment.
