Plasma created during electrical discharge machining is systematically investigated using optical emission spectroscopy. Typical spectra show a strong H-alpha and continuum radiation, with many lines emitted by impurities coming from electrode and workpiec ...
Objective: Quantitation of glutathione (GSH) in the human brain in vivo using short echo time 1 H NMR spectroscopy is challenging because GSH resonances are not easily resolved. The main objective of this study was to validate such quantitation in a clinic ...
The main aim of this work is to detect metabolites in the brain by means of nuclear magnetic resonance spectroscopy. We were mostly interested by glutathione (GSH) and more particularly by its cysteine part which forms a strongly coupled ABX spins system. ...
The detn. of residual dipolar couplings (RDCs) by quant. J spectroscopy methods such as heteronuclear single quantum correlation with phase encoded coupling (HSQC-PEC) is prone to systematic errors that may be caused by differential attenuation during the ...
We present the design, fabrication and test of high-Q factor radiofrequency planar microcoils for nuclear magnetic resonance (NMR) spectroscopy in small volume samples. The coils are fabricated on glass wafers using high-aspect ratio SU-8 photoepoxy and co ...
The synthesis and structural properties of three new hydridorhodium(III) complexes are reported. Hydrogenolysis of the cyclometalated Rh dichloride complexes [RhCl2{(S,S)-benbox(Me2)}] (2a-c; benbox(Me2) = 3,5-dimethyl-2,6-bis[(4-R1-4-R2-4,5-dihydrooxazol- ...
The detn. of residual dipolar couplings (RDCs) by quant. J spectroscopy methods such as heteronuclear single quantum correlation with phase encoded coupling (HSQC-PEC) is prone to systematic errors that may be caused by differential attenuation during the ...
The variable-speed magic-angle sample spinning (VSMAS) technique was extended to two-dimensional spectroscopy in solids yielding two-dimensional spectra free of spinning sidebands. [on SciFinder (R)] ...
In this thesis, the synthesis of oligomers of β-amino acids (β-peptides) is described. Their secondary structure is investigated by several techniques, in particular nuclear magnetic resonance (NMR) spectroscopy, but also circular dichroism and infrared sp ...
