Deuteron NMR spectra and relaxation were studied at the resonance frequency of 46 MHz in polycrystalline fully and partly deuterated ( NH 4 ) 2 ZnCl 4 between 300 and 5 K. Spectral components confirm existence of ammonium positions with different pot

The formation of astatide-mercury complexes was investigated in aqueous solutions. The obtained complexes were examined by paper electrophoresis. It was found that Hg(OH)At and Hg(OH)I complexes were formed in neutral solution. The stability constant

82Rb is a generator produced positron-emitting isotope (T1/2 = 75 s) that is increasingly being used in positron emission tomography for the characterization of myocardial perfusion. The parent radionuclide of 82Rb, strontium 82Sr, is produced mainly

The aim of this work was to check whether the stable cesium content in forest litter affects the value of radiocesium from litter-to-mushroom transfer factor Tf or not. Total cesium in litter, measured by AAS, varied from 0.1-2.7 micrograms/g. These

Partially deuterated ammonium compounds contain ammonium ion isotopomers with relative abundances given by the binomial distribution of protons and deuterons. All isotopomers with deuterons contribute characteristic deuteron NMR spectra at 5 K. Exper

A very efficient extraction of silver with tetrabutyl dithiopyrophosphate (TBDTPP) is followed by dramatic changes in the structure of the extractant molecule. The IR and NMR spectroscopic studies have revealed that in the presence of Ag+ and NO3−

Dissociation of Frenkel excitons in the neighbourhood of a charged defect in anthracene crystals is investigated in relation to the recent experimental results of Fort and Coret. The trimer model is adopted, and the charge-transfer integral relevant

The carbonyl stretching region of fully deuterated acetic acid CD3COOD in D2O has been studied by means of Raman spectroscopy. The number of linearly independent spectral components was determined to be four by factor analysis. Fourier self-deconvolu

The second-order correction to the interaction energy of two ground-state hydrogen atoms has been calculated by expanding (1) in terms of products of the gaussian orbitals. Satisfactory convergence was obtained in both the no-overlap and small-overla
