Zero-Field Nuclear Magnetic Resonance
Techniques for studying molecular structure, such as x-ray diffraction and nuclear magnetic resonance (NMR), often require the use of single crystals' or oriented samples. ' NMR, for example, is sensitive to interatomic distances and angles through spectral splittings caused by internucl. ear dipol. e-dipole couplings in high magnetic field. Where only polycrystalline powders or amorphous mater...
متن کاملParahydrogen-enhanced zero-field nuclear magnetic resonance
Nuclear magnetic resonance, conventionally detected in magnetic fields of several tesla, is a powerful analytical tool for the determination of molecular identity, structure and function. With the advent of prepolarization methods and detection schemes using atomic magnetometers or superconducting quantum interference devices, interest in NMR in fields comparable to the Earth’s magnetic field a...
متن کاملNear-zero-field nuclear magnetic resonance.
We investigate nuclear magnetic resonance (NMR) in near zero field, where the Zeeman interaction can be treated as a perturbation to the electron mediated scalar interaction (J coupling). This is in stark contrast to the high-field case, where heteronuclear J couplings are normally treated as a small perturbation. We show that the presence of very small magnetic fields results in splitting of t...
متن کاملZero-field nuclear magnetic resonance spectroscopy of viscous liquids.
We report zero-field NMR measurements of a viscous organic liquid, ethylene glycol. Zero-field spectra were taken showing resolved scalar spin-spin coupling (J-coupling) for ethylene glycol at different temperatures and water contents. Molecular dynamics strongly affects the resonance linewidth, which closely follows viscosity. Quantum chemical calculations have been used to obtain the relative...

appear which matched those observed by Sanchez and Spiro. Figure 9 shows the time development of the observed Raman spectrum at -0.8 V which at long times became the spectrum of high-spin Fe(I1). The time development of the spectroscopic changes at -0.8 V contrasts the instantaneous changes observed in the reduction of adsorbed hemin and instead tracks the slow reduction of the entire solution ...
