Finally the plane in which a water molecule is lying is determined by minimizing the sum of the squares of the distances of the two protons to their respective acceptor atoms.doi:10.1107/S0567740873004759BY R. DE BEERW. DE BOERC. A. VAN'T HOF...
The appearance thresholds and kinetic energy spectra of fragment protons and deuterons produced in the dissociative photoionization of H 2 O and D 2 O by 20–40 eV photons have been measured. Measurements were made both along and at right angles to the E vector of the synchrotron radiation to...

Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a ...
When the protons in CoCl 2 · 6H 2O were replaced by deuterons, the Néel temperature T N was found, using NMR techniques, to increase monotonically with the number of deuterons. T N increased by 6% when the percentage of deuterons was changed from 0% to 92%....
A proton magnetic resonance study of single crystals of Li(CH3COO).2H2O is reported. It confirms the earlier X-ray studies on the crystal by Galigne, Mouvet & Falgueirettes [Acta Cryst. (1970). B26, 368] and suggests a more probable location for the protons of the water molecules....
The transfer of H+ protons occurs through narrow, water-filled channels by means of the sulfonic-acid-terminated side chains (Figure 1). Figure 1. Gierke cluster-channel model of a swollen Nafion-type membrane. 2.2. P-H20 Synthesis The chemical structure of the asymmetric hyperbranched polymer...
