Nuclear Magnetic Resonance (NMR) spectroscopy has made a tremendous impact in many areas of chemistry, biology and medicine. In this report a student-oriented approach is presented, which enhances the ability of students to comprehend the basic concepts of NMR spectroscopy and the NMR spectra of various nuclei. The origin of chemical shifts, coupling constants, spin relaxation and the Nuclear O...

An absolute shielding scale is proposed for (207)Pb nuclear magnetic resonance (NMR) spectroscopy. It is based on ab initio calculations performed on an isolated tetramethyllead Pb(CH3)4 molecule and the assignment of the experimental resonance frequency from the gas-phase NMR spectra of Pb(CH3)4, extrapolated to zero density of the buffer gas to obtain the result for an isolated molecule. The ...

Abstract Optically induced nuclear spin–spin coupling in semiconductors is expected to serve for gate operations nuclear-magnetic-resonance (NMR) quantum computations. However, not much known about its characteristics. In this study, we investigate optically couplings GaAs via double-resonance spin-echo decay experiments under optical pumping. The squared echo rate $$\left( {1/T_2} \right)^2$$ ...

Nuclear magnetic resonance (NMR) is a phenomenon in which particular atomic nuclei respond to the application of certain magnetic fields by absorbing or emitting electromagnetic radiation, a phenomenon which was first demonstrated by Bloch, Hansen and Packard in 1946. Its medical application was pioneered by Odeblad, a physicist from Sweden, during the l950s and 1960s (Odeblad and Lindstr#{246}...

The nitrogen-vacancy (NV) center in diamond has enabled studies of nanoscale nuclear magnetic resonance (NMR) and electron paramagnetic with high sensitivity small sample volumes. Most NV-detected NMR (NV-NMR) experiments are performed at low fields. While fields useful many applications, high-field NV-NMR fine spectral resolution, signal sensitivity, the capability to observe a wider range nuc...

Protic ionic liquids have been regarded as promising materials to capture CO2, because they can be easily synthesized with an attractive capacity. In this work, we studied the CO2 absorption mechanism by protic (ILs) composed of diamino cations and azolide anions. Results 1H nuclear magnetic resonance (NMR), 13C NMR, 2-D NMR fourier-transform infrared (FTIR) spectroscopy tests indicated that re...

Nuclear Magnetic Resonance (NMR) is used to study the early-age hydration as well autogenous shrinkage and drying of cement paste with addition coir fibers. The dosage water content fibers are evaluated. results show that added have a negligible influence on kinetics. However, internal curing effect saturated competition induced by dry visualized. As fiber increases, decrease due reinforcing ef...

By now, it is obvious to me that the so called "overunity" devices as demonstrated by Tariel Kapanadze, Floyd Sweet, Steven Mark, Don Smith, Alfred Hubbard, SR193 and others, draw their energy from the nuclei located in material which forms a part of the device. They are, in effect, conversion devices, converting excess energy of the nuclei to electricity and/or heat. In these devices, the fuel...

Metallic and superparamagnetic DNA-templated nanoparticle (NP) chains are examined as potential imaging agents. Proton relaxation times (T(1) and T(2)) are measured for DNA nanostructures using nuclear magnetic resonance (NMR) spectroscopy. The layer-by-layer (LBL) method was used to encapsulate the DNA-templated NP chains and demonstrated a change in proton relaxation times. Results from this ...
