AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Multiple experiments (17O NMR, 1H NMR, and EPR) have been performed in the past to understand the microscopic parameters that control the magnetic relaxation rate enhancement induced by paramagnetic molecules on neighboring water protons, the so-called rel ...
A pulsed field gradient NMR (= nuclear magnetic resonance) method using stimulated echoes for determining the translational isotropic or anisotropic diffusion coefficient of a molecule or supramolecular assembly or the flow rate and direction of fluids con ...
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 theory of single-transition cross-polarization in NMR is presented and verified by exptl. evidence. In comparison to conventional cross-polarization a qual. change in the mechanism is obsd. Under the influence of matched radiofrequency fields with ampl ...
The interface between solid surfaces and cavities filled with gaseous 131Xe can be probed by multiple-quantum filtered NMR. Physisorbed 131Xe is usually not directly observable by NMR spectroscopy, but information can be transferred into the gas phase thro ...
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 ...
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 ...
The experimental determination of slice profiles excited by applying radiofrequency pulses in the presence of a gradient generally results in magnitude profiles. The conditions necessary to obtain a phase-sensitive picture of the profile of a slice are dis ...
In this paper we demonstrate experimentally that the continuously phase-modulated homonuclear decoupling sequence DUMBO-1 is suitable for high-resolution proton NMR spectroscopy of rigid solids. Over a wide range of experimental conditions, we show on the ...
