Intermolecular hydrogen bond and its spectroscopic manifestations in formation of small water complexes

Ab initio calculations of small water(H ₂ O) _n , n=2–7, complexes and the experimental evidence available are compared. The results obtained are used as a basis for a theoretical investigation into the water molecule association through hydrogen bonding and its spectroscopic manifestations. Basic structural and spectroscopic trends are established as the complex increases in size. Siberian Physicotechnical Institute at Tomsk State University.
