چکیده

The surface of γ-alumina nanoparticles can be characterized by dynamic nuclear polarization (DNP) surface-enhanced NMR of (27)Al. DNP is combined with cross-polarization and MQ-MAS to determine local symmetries of (27)Al sites at the surface.

Solid-State Polarization-Transfer Experiments Involving Quadrupolar Nuclei

Historically, cross-polarization experiments [1,2] have been used to transfer spin coherence from abundant spins to a dilute spin system. Protons (*H) have been used almost exclusively as the source of strong nuclear polarization for cross-polarization experiments, although there have been some examples where other abundant nuclei have been used. Coupled with magic-angle spinning (MAS) NMR [3],...

Cross polarization from (1)H to quadrupolar (6)Li nuclei for dissolution DNP.

Cross polarization from protons to quadrupolar (6)Li nuclei is combined with dynamic nuclear polarization of protons at 1.2 K and 6.7 T using TEMPOL as a polarizing agent followed by rapid dissolution. Compared to direct (6)Li DNP without cross-polarization, a higher nuclear spin polarization P((6)Li) can be obtained in a shorter time. A double resonance (1)H-(6)Li probe was designed that is eq...

Surface enhanced NMR spectroscopy by dynamic nuclear polarization.

It is shown that surface NMR spectra can be greatly enhanced using dynamic nuclear polarization. Polarization is transferred from the protons of the solvent to the rare nuclei (here carbon-13 at natural isotopic abundance) at the surface, yielding at least a 50-fold signal enhancement for surface species covalently incorporated into a silica framework.

NMR of Insensitive Nuclei Enhanced by Dynamic Nuclear Polarization.

Despite the powerful spectroscopic information it provides, Nuclear Magnetic Resonance (NMR) spectroscopy suffers from a lack of sensitivity, especially when dealing with nuclei other than protons. Even though NMR can be applied in a straightforward manner when dealing with abundant protons of organic molecules, it is very challenging to address biomolecules in low concentration and/or many oth...

High-Field Cross Polarization NMR from Laser-Polarized Xenon to Surface Nuclei

Abstraet. A method for NMR investigations of surface nuclei using cross polarization from optically polarized xenon (OPCP) is descfibed. We find this methodology results in enhancement faetors of approximately 103 upon application to surface protons. The dynamics of 129Xe transfer to protons is examined in some detail, including the time, temperature, and multiple contact dependences of signal ...
