Formula omitted] and [formula omitted] nuclear quadrupole double-resonance study of several hydroxide compounds. II. The water molecule

Abstract

Using the technique of double resonance with coupled multiplets at 77 K and room temperature, 17O double-resonance signals were detected from the H 2O molecules in a number of hydrates of the alkali metal and alkaline earth metal hydroxides at natural abundance. The deuteron double-resonance signals were measured in deuterated samples at 77 K using double resonance by level crossing. The correlations between the 17O and 2H quadrupole coupling constants and the hydrogen bond strength are discussed. The 17O DRCM results for BeSO 4 · 4H 2O are included.
