Electron density distribution studies of compounds containing sulfur–sulfur bond

Positron Annihilation Studies of f-Electron Compounds

We present a theoretical analysis of positron annihilation studies of two isostructural f -electron compounds CeIn3 and UGa3. The interpretation of twodimensional angular correlation of annihilation radiation experiment (2D-ACAR) is based on a parameter-free density functional theory calculations. Our analyses show, that the f -electrons in CeIn3 behave as well localized while in UGa3 it was th...

Electron-positron momentum density distribution in diamond

We have measured the momentum distribution of the electron-positron annihilating pair in diamond as a function of crystallographic orientation, using the Doppler broadening technique of positron annihilation spectroscopy. A 1% variation in the longitudinal projection of the momentum distribution was observed as the sample was rotated about the (110) axis. This anisotropic distribution shows an ...

Studies of bromine-oxidizable sulfur-containing compounds in mold metabolism.

Studies of enzyme inhibition by compounds containing small rings.

Our interest in the enzyme chemistry of compounds containing small rings developed from a speculative study of the inhibition of alcohol dehydrogenase by allylic alcohols (MacInnes et al., 1981) in which we found that 3-thioethylprop-2-en1-01 (I) was a potent inhibitor of this enzyme. Our original strategy was that oxidation of (I) would lead to an a,/?-unsaturated aldehyde to which a nucleophi...

Power law relationships between bond length, bond strength and electron density distributions

R.T. Downs Department of Geological Sciences, University of Arizona, Tucson, AZ 85721, USA Abstract The strength of a bond, defined as p=s/r, where s is the Pauling bond strength and r is the row number of an M cation bonded to an oxide anion, is related to a build-up of electron density along the MO bonds in a relatively large number of oxide and hydroxyacid molecules, three oxide minerals and...
