Phosphorus-31 NMR spectroscopy using a loop-gap resonator
(Elsevier: Journal of Magnetic Resonance, 1986-06-15)
The loop-gap resonator provides a simple and convenient alternative for large volume probes that are now practical for applications to NMR spectroscopy. A 400 ml probe is described for use in a large-bore magnet which is ...
Photoreactions of the triruthenium cluster Ru3(CO)12 and substituted analogs
(The American Chemical Society: Journal of the American Chemical Society, 1986-04-16)
Reported is a comprehensive investigation of the medium, ligand, and wavelength effects on the quantum yields and flash photolysis kinetics for the photofragmentation and photosubstitution reactions of the trinuclear ...
Diffusion coefficients in anisotropic fluids by ESR imaging of concentration profiles
(American Institute of Physics: The Journal of Chemical Physics, 1986-03-15)
We report on the use of ESR imaging for determining the translational diffusion constants of typical ESR spin probes in ordered and isotropic solvents. A discussion is given for a Fourier deconvolution method for determining ...
Temperature dependence of the reaction hydroperoxo (HO2) + hydroperoxo at low pressures
(The American Chemical Society: Journal of Physical Chemistry, 1986-02-13)
The temperature dependence of the self-reaction of HO2, HO2 + HO2 -> H2O2 + O2 (k1) (1), was investigated by detecting HO2 with laser magnetic resonance in a low-pressure flow tube coated with halocarbon wax. Two independent ...
Heterogeneous electron-transfer kinetics for some multiply bonded dirhenium complexes
(Elsevier: Journal of Electroanalytical Chemistry, 1985-12-10)
Standard electrochemical rate constants kexob have been measured for the two sequential one-electron oxidations of triply-bonded dirhenium(II) complexes Re2X4(PR3)4, where X = Cl or Br, and PR3 = a monodentate tertiary ...
Two-dimensional complex Fourier-transform via the radon-transform
(Optical Society of America, 1985-11)
A hybrid system has been constructed to perform the complex Fourier transform of real two-dimensional data. The system is based on the Radon transform; i.e., operations are performed on one-dimensional projections of the ...
Evaluation of two viral inactivation methods for the preparation of safer factor VIII and factor IX concentrates
(Blackwell Publishing: Transfusion, 1985-11)
We report here the results of our evaluation of two procedures to eliminate viruses in factor VIII and factor IX coagulation factor concentrates. Both procedures were equally effective in the in vitro destruction of marker ...
Energy costs of subduing and swallowing prey for a lizard
(The Ecological Society of America: Ecology, 1985-10)
We measured the oxygen consumption (aerobic energy cost) and lactic acid production (anaerobic energy cost) of scincid lizards, Chalcides ocellatus, eating domestic crickets. Aerobic metabolism accounted for 90% or more ...
Small-period electromagnet wigglers for free-electron lasers
(American Institute of Physics, 1985-09-15)
A new configuration for wiggler magnets compatible with free-electron laser (FEL) deployment is described and demonstrated experimentally. The configuration is simple and inexpensive to fabricate and allows for continuous ...
Solvent effects on the kinetics of simple electrochemical reactions. Further examination of metal ethylenediamine and ammine redox couples.
(Elsevier: Journal of Electroanalytical Chemistry, 1985-09-10)
The dependence of the kinetics of Co(en)33+/2+ exchange (en=ethylenediamine) at mercury electrodes upon the nature of the solvent is discussed further by examining the preexponential factors, Acorr, as well as double-layer ...
