A computed list of HD16O infrared transition frequencies and intensities is presented. The list, VTT, was produced using a discrete variable representation two-step approach for solving the rotation–vibration nuclear motions. The VTT line list contains almost 700 million transitions and can be used to simulate spectra of mono-deuterated water over the entire temperature range that are of import...

We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40 N in October 2002. Strong deuterium enrichments of up to 400‰ versus Vienna Standard Mean Ocean Water (VSMOW) are observed, while the H2 mixing ratio remains virtually constant. Thus, as hydrogen is p...

Solvent deuterium isotope effects support the view that the p-N02 and p-Me derivatives of benzaldehyde S.S-diethylacetal undergo silver ion-promoted hydrolysis in water by different mechanisms. scheme common [3] for O.O-acetals in the presence of H30 + ions, while for the latter we suggested a bimolecular A2-type mechanism with one (or more) water molecules in the slow phase of step (3). The co...

The study of chemical transformations in the living cell with the aid of the isotope technique requires the preparation of deuterio compounds which contain deuterium atoms linked to carbon atoms. The carbon-deuterium linkages must be stable in the sense that the deuterium atoms will not be replaced by hydrogen atoms on solution in water. In the case of simple organic compounds, standard synthet...

The body cell mass (BCM), defined as intracellular water (ICW), was estimated in 73 healthy men and women by total body potassium (TBK) and by bioimpedance spectroscopy (BIS). In 14 other subjects, extracellular water (ECW) and total body water (TBW) were measured by bromide dilution and deuterium oxide dilution, respectively. For all subjects, impedance spectral data were fit to the Cole model...

When fertilized and unfertilized eggs of Arbacia punctulata are suspended in heavy water, deuterium is incorporated into stable positions in the egg proteins. The rate of incorporation of the isotope is considerably greater in fertilized than in unfertilized eggs, and is accelerated at the time of formation of the blastula. The result of calculation of the maximum deuterium concentration which ...
