Ultrahigh-Resolution Magnetic Resonance in Inhomogeneous Magnetic Fields: Two-Dimensional Long-Lived-Coherence Correlation Spectroscopy

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Riddhiman Sarkar, Srinivas Chinthalapalli

A half-century quest for improving resolution in Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) has enabled the study of molecular structures, biological interactions, and fine details of anatomy. This progress largely relied on the ...

Improved lipid profiling of the mouse liver by 1H-NMR spectroscopy at 14.1T in vivo

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

Purpose/Introduction: Whole-body metabolic deregulation features changes in hepatic lipid dynamics. In vivo 1H-MRS allows to noninvasively assess hepatic lipid content (HLC) and composition both in humans [1] and rodents [2]. Transgenic mice provide insigh ...

Extending Timescales and Narrowing Linewidths in NMR

Geoffrey Bodenhausen, Aurélien Bornet, Pascal Miéville, Sami Jannin, Diego Carnevale, Paul Romeo Vasos, Simone Ulzega, Marc Anthony Caporini, Nicola Salvi, Martial Rey

Among the different fields of research in nuclear magnetic resonance (NMR) which are currently investigated in the Laboratory of Biomolecular Magnetic Resonance (LRMB), two subjects that are closely related to each other are presented in this article. On t ...

Structural Composition of First-Neighbor Shells in GeSe2 and GeSe4 Glasses from a First-Principles Analysis of NMR Chemical Shifts

Alfredo Pasquarello, Carlo Massobrio, Mikhail Kibalchenko

Isotropic chemical shifts and quadrupole coupling parameters of Se-77 and Ge-73 nuclei in GeSe2 and GeSe4 glasses are determined through density-functional NMR calculations on amorphous model structures generated by ab initio molecular dynamics. The compar ...

Second order proton traps for multi-nuclear RF coils: Applied for 13C MRS in humans at 7T

Rolf Gruetter

The concept of second order proton traps (consisting of an inductor and two capacitors) in coils for non-proton NMR allows control over the resonance frequency, the blocking frequency and the trap mode frequency. Effective proton traps with relatively high ...

Line-narrowing in proton-detected nitrogen-14 NMR

Geoffrey Bodenhausen, Simone Cavadini, Simone Ulzega

In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...

Improved ¹H-[¹³C] and ¹H NMR methods for in vivo measurement of cerebral metabolism

Lijing Xin

Nuclear magnetic resonance (NMR) spectroscopy can be applied in vivo to measure static or dynamic biochemical information, e.g., concentrations of metabolites and metabolic fluxes, using various nuclei such as 1H, 13C, 31P and 15N. The work of this thesis ...

Search for nuclear magnetic resonance evidence of spin accumulation

Aurore Rudolf

Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...

Long-lived states to sustain hyperpolarized magnetization

Geoffrey Bodenhausen, Jean-Philippe Ansermet, Arnaud Comment, Sami Jannin, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

Major breakthroughs have recently been reported that can help overcome two inherent drawbacks of NMR: the lack of sensitivity and the limited memory of longitudinal magnetization. Dynamic nuclear polarization (DNP) couples nuclear spins to the large reserv ...

Singlet-state exchange NMR spectroscopy for the study of very slow dynamic processes

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar

Solution-state nuclear magnetic resonance method for singlet-state nuclear magnetic resonance-spectroscopy, involves performing transformation of zero-quantum coherences into singlet-state populations by radio frequency irradiation ...
