Summary
The influence of Na+ on hydrogen bonds of the OH ⋯ O and NH ⋯ O type between an aliphatic amino acid (glycine zwitterion) and water is investigated byab initio calculations with minimal Gaussian basis sets. Distortion of the hydration shell caused by Na+, and interaction energies contributing to the over-all stabilization are discussed.
Zusammenfassung
Der Einfluß von Na+ auf die Wasserstoffbindungen vom OH ⋯ O- und NH ⋯ O-Typ in aliphatischen Aminosäuren (Glycin-Zwitterion) und Wasser wurde mittelsab initio Berechnungen mit einem minimalen Gausschen Basissatz untersucht. Die durch Na+-Ionen hervorgerufenen Verzerrungen der Hydratationsschale und die zur Gesamtstabilisierung beitragenden Wechselwir-kungsenergien werden diskutiert.
