For the past decade, nuclear magnetic resonance (NMR) has been established as a main experimental technique for testing quantum protocols in small systems. This Theme Issue presents recent advances and major challenges of NMR quantum information possessing (QIP), including contributions by researchers from 10 different countries. In this introduction, after a short comment on NMR-QIP basics, we...

Experimental realization of quantum information processing in the field of nuclear magnetic resonance (NMR) has been well established. Implementation of conditional phase-shift gate has been a significant step, which has lead to realization of important algorithms such as Grover's search algorithm and quantum Fourier transform. This gate has so far been implemented in NMR by using coupling evol...

We present nuclear spin-rotation constants, absolute nuclear magnetic resonance (NMR) shielding constants, and shielding spans of all the nuclei in (175)LuX and (197)AuX (X = (19)F, (35)Cl, (79)Br, (127)I), calculated using coupled-cluster singles-and-doubles with a perturbative triples (CCSD(T)) correction theory, four-component relativistic density functional theory (relativistic DFT), and no...

This chapter gives an introduction to automated nuclear magnetic resonance (NMR) structure calculation with the program CYANA. Given a sufficiently complete list of assigned chemical shifts and one or several lists of cross-peak positions and columns from two-, three-, or four-dimensional nuclear Overhauser effect spectroscopy (NOESY) spectra, the assignment of the NOESY cross-peaks and the thr...

Nuclear magnetic resonance medical imaging is a new diagnostic tool available to radiologist for investigating the morphology and pathophysiology of the human body. In the presence of constant, stable, and uniform magnetic field and the application of radiofrequency radiation, will enable to produce anatomic cross sections. The physical principles of nuclear magnetic resonance medical imaging a...

Wehave studied nuclear effects on electron spins in lightly doped n-GaAs bulk and quantumwell samples using optically detected magnetic resonance, with the optical detection done via Kerr rotation. The magnetic resonance signal allowed us to measure the electron T ∗ 2 lifetimes and g-factors. We observed strong dynamic nuclear polarization, which was controllable via nuclear magnetic resonance ...

The detailed conformational features and dynamics of the naturally occurring deoxyribotrinucleoside diphosphates d-TpTpT and d-TpTpC have been investigated at 20 degrees C and 80 degrees C in aqueous solution by nuclear magnetic resonance spectroscopy. The observed NMR parameters indicate that the conformational properties of the trimers are very similar to those of the constituent dimers and m...

In this Letter, we present NMR spin-lattice and relaxometry data for proton transfer in one of the shortest known N-H⋯O hydrogen bonds in a single crystal of 3,5 pyridinedicarboxylic acid (35PDCA). It is widely believed that proton transfer by quantum tunneling does not occur in short hydrogen bonds since the ground state energy level lies above the potential barrier, yet these data show a temp...

The rheology is widely known as one of the basic methods for rubber investigations for many years. At the same time, a variety of other methods of physical and chemical analysis suitable is available for rubber industry. One of them, the Time-Domain Nuclear Magnetic Resonance (TD--NMR) Spectroscopy is very sensitive to structural properties of elastomer materials. Moreover, by using NMR it is p...

background hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. percutaneous liver biopsy; however, is an invasive procedure with risks of complications. therefore, there is need for alternative non-invasive techniq...
