Aqueous Nonelectrolyte Solutions. Part VIII. Deuterium and Hydrogen Sulfides Solubilities in Deuterium Oxide and Water

Aqueous Solutions of Deuterium Oxide

The differences between the boiling points of dilute aqueous solutions of heavy water and the boiling point of ordinary water were measured in the range from 0.3 to 7 percent of D 20. The boiling points were found to increase linearly with increase in D 20, according to the equation mole % of D20 = 70.9 (tJ.T), where tJ.T is the boiling point in degrees centigrade minus 100. The measmements, ma...

Carboxypeptidasey from Saccharomyces cerevisiae Conformational Difference Reflected in Kinetic Behaviour in Water and Deuterium Oxide

Solar System Deuterium/Hydrogen Ratio

The D/H variations in chondritic meteorites are reviewed and compared with astronomical observations in the interstellar medium. The observed D enrichment in organic molecules — and to a lesser extent in water — is a general rule in the universe. The D is preferentially transferred from the universal reservoir (H2) by low-temperature reactions (10–100 K) from neutral molecules (H2 or H) to hot ...

Zemach Moments for Hydrogen and Deuterium

We determine the Zemach moments of hydrogen and deuterium for the first time using only the world data on elastic electron-proton and electron-deuteron scattering. Such moments are required for the calculation of the nuclear corrections to the hyperfine structure of these hydrogenic atoms. We compare the resulting HFS predictions to the available high-precision data and provide an estimate of t...

Lamb Shift of Muonic Deuterium and Hydrogen

My previous calculations of the Lamb shift in muonic hydrogen are reviewed and compared with other work. In addition, numerical results for muonic deuterium are presented. Introduction The energy levels of muonic atoms are very sensitive to effects of quantum electrodynamics (QED), nuclear structure, and recoil, since the muon is about 206 times heavier than the electron [1]. A number of theore...
