Book Description :

Deuterium: Discovery and Applications in Organic Chemistry provides a well-illustrated overview of the discovery of 2H or heavy hydrogen, the stable hydrogen isotope with both a proton and a neutron in its nucleus. The work introduces the isotope, its discovery, physical properties, nomenclature, and common compounds, also exploring its application in organic chemistry through classic and recent examples from literature. Finally, the book devotes one chapter to Deuterium in medicinal chemistry and the biological effects of Deuterium Oxide, better known as D2O. Provides unique coverage not found elsewhere that is presented in an accessible, dedicated short work Contains practical information and examples on the use of Deuterium (D or 2H, Heavy Hydrogen) in organic synthesis Presents a detailed description of Deuterium’s discovery and applications in the pharmaceutical industry

Book Description :

In 1931 Vrey, Brickwedde, and Murphy discovered the hydrogen isotope deuterium. The isotopic enrichment was found to arise from the fact that the electrolysis oflight water is faster than of heavy water [1,2]. This success showed that although different isotopes of an element behave identically from a chemical standpoint the different isotopic masses nevertheless lead to both isotope effects on equilibrium as well as on rate constants of chemical reactions. Soon, ratios of equilibrium constants of isotopic reactions were called "equilibrium isotope effects" (EIE), ratios of isotopic rate constants "kinetic isotope effects" (KIE). Isotope effects have been found to be especially large for those elements which are directly involved in bond breaking and bond formation during the reaction studied [3]. Such effects are, therefore, referred to as "primary". Isotopic substitution in atomic sites which maintain all chemical bonds with their neighbors during the reaction of interest leads then only to smaller "secondary" isotope effects. Because of the unique mass relation between the different hydrogen isotopes hydrogen/deuterium isotope effects are particularly large and have attracted most attention. The largest contributions to these effects arise from changes in the vibrational frequencies of the reactants. The theory of equilibrium isotope effects has been founded by Vrey [4] and Bigeleisen [5,6] and has widely been accepted [3].

Book Description :

Abstract: As the energy resources running out, scientists are trying to provide sustainable energy. They move toward the hydrogen economy although it has large technical difficulties that need to be solved. Hydrogen is considered as a clean fuel. Storing hydrogen using clathrate hydrates is one of the promising ways to provide required energy. The high hydrogen content in sII clathrate hydrate proposes some applications like replacing gasoline to fuel vehicles, using as a gas separation substance, and transporting some dangerous gases. In addition, clathrate hydrate is found in nature in huge amounts. Generally speaking, it is approximated that about 3000 billion tons of carbons of clathrate hydrates exist as a worldwide reserves. This large amount can replace usual fossil fuel like oil and coal, and be a new energy source. All what we need is to investigate these compounds and find the ways to make use of them. Clathrate hydrates are inclusion compounds, physically resembles ice, can trap a guest small non polar molecule behind walls made by water via confining the guest molecules by a definite structure. So, it isn't a chemical storage but physical. From the historical point of view, it is thought that the hydrogen and its isotopes are very small to make clathrate compounds stable but, recently, it is used to build a simple cubic structure II with water molecules. Formation of clathrate hydrates depends on the applied high pressure, low temperature, and the guest molecule. In this research, a full detailed picture of deuterium clathrate hydtare including structure, occupancy number per cage, deuterium dynamics, and ortho-para conversion of deuterium inside the cages has been conducted. The storage of deuterium in clathrate hydrate has been tested, and basal concepts of enclathrated deuterium have been evaluated. Manifold cavity occupation and small inter-molecular separation are some new exciting aspects. The small cages of sII structure can contain one deuterium molecule which represents deuterium content of 1.0 wt%. Raman spectroscopy is an important tool to study the dynamics of the trapped deuterium and the occupancy of deuterium inside the cages of the clathrate hydrate. It shows the vibrational and rotational bands of deuterium molecules. In sII hydrates, we have two types of cages: small cages and large cages. Enclathrated deuterium at all cages vibrates at lower frequency than free gas phase. In addition, the single deuterium occupied cages vibrates at lower frequency than multiple deuterium occupied cages. Raman spectra was collected from many samples of in-situ prepared deuterium clathrate placed in a cell to see the formation of the clathrate structure and the changes occur while applying heating and quenching cycles. Analysis of the vibrational bands of different cages has been explored and calculations regarding average occupancy number have been done.
