Optical emission spectroscopy of electrical discharge machining plasma

Christoph Hollenstein, Antoine Descoeudres

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 ...

High resolution photodetachment spectroscopy of negative ions via slow photoelectron imaging

Andreas Osterwalder

A technique for high resoln. anion photodetachment spectroscopy is presented that combines velocity map imaging and anion threshold photodetachment. This method, slow electron velocity-map imaging, provides spectral line widths of better than 1 meV. Spectr ...

High-Q factor RF planar microcoils for micro-scale NMR spectroscopy

Giovanni Boero, Radivoje Popovic, Pierre-André Besse, Franck Vincent, Charles Massin

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 ...

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 ...

ETH Zurich2000

The performance of deuterium-carbon correlation (DECOR) spectroscopy for the assignment and measurement of deuterium quadrupolar couplings in fully deuterated liquid crystalline phases is analyzed. The experiment relies on a broadband polarization transfer ...

AMER CHEMICAL SOC1998

NMR spectroscopy is one of the newer spectroscopic techniques for investigating the static, dynamic and electronic structures of molecules adsorbed onto metal catalyst surfaces. We review recent progress in the application of solid-state NMR methods to the ...

1997

A 2 + 1 double-resonance laser-induced fluorescence technique is described in which the high power of a pulsed laser is combined with the narrow bandwidth of a single-mode cw ring dye laser. The combination of these laser systems allows the study of highly ...

The difference between 1H NMR spectra obtained during eu- and hyperglycemia exhibited well-resolved glucose peaks between 3 and 4 ppm as demonstrated by comparison with solution spectra. Estimated increases were consistent with recent 13C NMR quantitations ...
