The observation of nuclear Overhauser effects (NOEs) between bound water and biol. macromols. such as proteins and nucleic acids can be improved by inverting the water resonance selectively while compensating for radiation damping effects. The efficiency o ...
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 ...
Coherent and dissipative phenomena induced by transient adsorption of xenon-131 on a glass surface were studied by NMR spectroscopy. The authors report the results of multiple-quantum filtered expts. over a range of temps., covering different relaxation re ...
The measurement of the migration of longitudinal 2-spin order by 2-dimensional (2D) exchange spectroscopy or by selective 1-dimensional (1D) methods (2D or 1D zz-exchange spectroscopy) allows unambiguous differentiation between chem. exchange and cross-rel ...
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 ...
New 2-dimensional NMR correlation methods are presented which allow one to obtain selected high-resoln. multiplets where all signals have pos. pure absorption peak shapes. The multiplets do not suffer from any cancellation effects, and their fine structure ...
New NMR techniques are described for transferring transverse magnetization between scalar-coupled nuclei in the rotating frame. The methods involve simultaneous spin-locking of two selected spins A and X, using cosinusoidal modulation of the radio frequenc ...
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 ...
It is shown how selective high resoln. 2-dimensional NMR spectra can be obtained which feature multiplets where all peaks have the same pos. sign and pure absorption lineshapes. [on SciFinder (R)] ...
Magnetic resonance spectroscopy (MRS) measurements of the lactate methyl proton in rat brain C6 glioma tissue acquired in the presence of an off- resonance irradiation field, analyzed using coupled Bloch equation formalism assuming two spin pools, demonstr ...
