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 کاملTIME-DOMAlN ZERO-FIELD MAGNETIC RESONANCE WITH FIELD PULSE EXCITATION
The principal attraction of magnetic resonance in zero field is the isotropy of space which allows one to record high-resolution spectra even for powder samples. This extends the domain of magnetic resonance to systems of which large single crystals cannot be grown. Normally, senslhvlty considerations do not pernut direct observation of zero-field resonance and special high-sensltlvity procedur...
متن کاملParahydrogen-induced polarization at zero magnetic field.
We use symmetry arguments and simple model systems to describe the conversion of the singlet state of parahydrogen into an oscillating sample magnetization at zero magnetic field. During an initial period of free evolution governed by the scalar-coupling Hamiltonian HJ, the singlet state is converted into scalar spin order involving spins throughout the molecule. A short dc pulse along the z ax...
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...
