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.
The temp. dependence of NMR relaxation rates was investigated for the backbone of 15N/13C labeled human ubiquitin in the temp. range of 20-50 DegC. The 15N autorelaxation rates give evidence that the potential energy functions for 15N-HN bonds are not quad ...
Nuclear Magnetic Resonance (NMR) spectroscopy offers many ways to investigate dynamic properties of molecules. A wide variety of experimental techniques can probe molecular dynamics on time scales that range from 10-12 to 103 seconds. Many lines of evidenc ...
Nuclear spin-lattice relaxation measurements were performed on Co-based magnetic nanowires, in zero field and in 1 T applied field. A measurement method is developped that allows a confident interpretation of the experimental data. An enhanced relaxation d ...
Overhauser effects and hence internuclear distances can be measured accurately with selective expts. designed to suppress spin diffusion. It is essential to consider effects of both transverse and longitudinal relaxation during selective radiofrequency pul ...
Nuclear magnetic resonance is a powerful nonintrusive technique for measuring diffusion coefficients through the use of pulsed field gradients. The main limitation to the application range of this method is imposed by the relaxation time constants of the m ...
Several methods are presented for the selective determination of spin-lattice and spin-spin relaxation rates of backbone protons in labeled proteins. The relaxation rates of amide protons in (15)N labeled proteins can be measured by using two-way selective ...
Theoretical and experimental investigations of the relaxation rates of multiple-quantum coherences during heteronuclear double resonance (HDR) pulse sequences are presented. Average Liouvillian theory yields analytical expressions to describe the effective ...
The temp. dependence of NMR relaxation rates was investigated for the backbone of 15N/13C labeled human ubiquitin in the temp. range of 20-50 DegC. The 15N autorelaxation rates give evidence that the potential energy functions for 15N-HN bonds are not quad ...
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 ...
The principle of quenching undesirable indirect external trouble in nuclear Overhauser effect spectroscopy (QUIET-NOESY) relies on a doubly selective inversion of the longitudinal magnetization components of a source spin A and a target spin X to measure t ...
