Atomic Nuclei: Nuclear Spin State Overview01:03

Atomic Nuclei: Nuclear Spin State Overview

2.2K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...

NMR Spectroscopy: Spin–Spin Coupling

3.6K
The spin state of an NMR-active nucleus can have a slight effect on its immediate electronic environment. This effect propagates through the intervening bonds and affects the electronic environments of NMR-active nuclei up to three bonds away; occasionally, even farther. This phenomenon is called spin–spin coupling or J-coupling. Coupling interactions are mutual and result in small changes in the absorption frequencies of both nuclei involved. While nuclei of the same element are involved...

Spin–Spin Coupling Constant: Overview

1.6K
In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...

Spin–Spin Coupling: One-Bond Coupling01:17

Spin–Spin Coupling: One-Bond Coupling

1.6K
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...

Atomic Nuclei: Nuclear Spin

5.5K
All atomic particles possess an intrinsic angular momentum, or 'spin'. Electrons, protons, and neutrons each have a spin value of ½, although protons and neutrons in nuclei may have higher half-integer spins owing to energetic factors.
Atomic nuclei have a net nuclear spin, , which can have an integer or half-integer value. In atomic nuclei, the spins of protons are paired against each other but not with neutrons, and vice versa. Consequently, an even number of protons does not contribute to...

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

Area of Science:

  • Quantum physics
  • Condensed matter physics
  • Materials science

Background:

  • Topological defects, specifically edge states in dimerized spin chains, offer protection from decoherence.
  • Understanding relaxation and decoherence is crucial for implementing these systems in quantum devices.

Purpose of the Study:

  • Investigate the quantum dynamics of electron spin resonance in topological defects.
  • Identify relaxation and decoherence sources in dimerized spin chains.
  • Establish design principles for optimizing coherence in future materials.

Main Methods:

  • Quantum many-body theory applied to spin chains.
  • Analysis of electron spin resonance dynamics.
  • Temperature-dependent relaxation and decoherence studies.

Main Results:

  • Electron spin lattice relaxation is governed by phonon-bottlenecking at low temperatures and the dimerization gap at high temperatures.
  • Intrachain exchange coupling reduces inter-edge state dipolar fields, enhancing coherence time.
  • Homogeneous broadening is primarily determined by the intrachain dipolar field.

Conclusions:

  • Topological defects in dimerized chains exhibit protected quantum many-body multiplets.
  • Coherence times can be extended by mitigating intra-chain dipolar fields.
  • Design principles are established for developing robust quantum materials based on these findings.
