Field gradient techniques in NMR spectroscopy
Current Opinion in Structural Biology, 1995In recent years NMR spectroscopy has emerged as a powerful technique for studying the structure and dynamics of biomolecules in solution. The development of shielded pulsed-field gradient coils for high-resolution NMR spectroscopy has led to significant improvements in a large number of experiments which are used to provide such information ...

Near-field spectroscopy of nanostructures
SPIE Proceedings, 2010ABSTRACT We report a new near-field Raman imaging technique by tra pping and scanning a dielectric microsphere over a sample surface in water. This method has a few critical advantages over both aperture and apertureless near-field Raman techniques, such as strong near-field signal, high reproducibilit y, high resolution and cheap cost. In this method,

Abstract The Earth's magnetic field provides a convenient B 0 for performing magnetic resonance spectroscopy experiments. Providing certain environmental factors that can be overcome, the natural homogeneity of the Earth's field results in NMR signals with very narrow linewidths.

Integral Field Spectroscopy with VIMOS
2008In addition to its standard direct imaging and multi-object spectroscopy modes, VIMOS offers an option for integral field (3D) spectroscopy using an unprecedentedly large integral field unit Integral-Field Unit (IFU). With a total of 6400 spectracovering a maximum field-of-view (FoV) of 54”×54”, this mode presentssome challenges in terms of data ...

Spectroscopy in Megagauss fields: Theory
AIP Conference Proceedings, 1990We report on how the recent numerical solution of the problem of a hydrogen atom in a magnetic field of arbitrary strength ‐one of the remaining ’unsolved elementary problems in atomic physics’ (Kleppner et al.) ‐has helped in identifying the mysterious line features unexplained for almost five decades in the optical spectrum of the white dwarf star ...

Field Emission Spectroscopy of Metals
1984A theory of field emission which takes into account the energy-band-structure of the metal emitter was initially proposed by Itskovich (1966, 1967). The next significant step was made by Politzer and Cutler (1972). Their calculation of the spin-polarized field emission current from ferromagnetic nickel (100) constitutes the first serious attempt to ...
