Methylene-only subspectra in (13)C CPMAS using a new double quantum filtering sequence

Methodology for the assignment of (13)C CPMAS spectra is still in its infancy. Previous methods of CPMAS spectral editing have utilized differences in the strength of the (13)C-(1)H dipolar interaction or the rate and spin thermodynamics of crosspolarization from protons to carbon, to differentiate between quaternary, tertiary, and methylene carbons. We introduce a different approach, which is ...

Lactate Detection Using Double Quantum Coherence Filtering with Spectral-Spatial Refocusing RF Pulses in a PRESS Sequence

Introduction: Double-quantum coherence filtering (DQF) with PRESS localization has been used for spectral editing in MRS [1]. Previous studies have shown that DQF with PRESS can selectively detect signals from metabolites such as lactate. However, these techniques face several challenges [2]. For example, chemical shifts among different metabolites can result in spatial mismatch of the slice-se...

Electron–nuclear interaction in 13C nanotube double quantum dots

For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a dominant source of unwanted spin decoherence1–3 or, if controlled effectively, a resource enabling storage and retrieval of quantum information4–7. To investigate the effect of a controllable nuclear environment on the evolution of confined electron spins, we have fabricated and measured gate-defined ...

Probing molecular motion by double-quantum (13C,13C) solid-state NMR spectroscopy: application to ubiquitin.

We demonstrate the use of two-dimensional ((13)C,(13)C) double-quantum spectroscopy to detect molecular dynamics by solid-state NMR. Data collected on tyrosine-ethylester (TEE) are in line with previously determined ((1)H,(13)C) order parameters. Application of these experiments to microcrystalline ubiquitin reveals the presence of dynamics on millisecond or faster time scales and differences i...

Relaxation and dephasing in a two-electron 13C nanotube double quantum dot.

We use charge sensing of Pauli blockade (including spin and isospin) in a two-electron 13C nanotube double quantum dot to measure relaxation and dephasing times. The relaxation time T1 first decreases with a parallel magnetic field and then goes through a minimum in a field of 1.4 T. We attribute both results to the spin-orbit-modified electronic spectrum of carbon nanotubes, which at high fiel...
