Double Resonance Techniques: Overview01:12

Double Resonance Techniques: Overview

247
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

¹³C NMR: ¹H–¹³C Decoupling

1.1K
The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...

Atomic Nuclei: Magnetic Resonance

The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

NMR Spectroscopy: Spin–Spin Coupling

1.5K
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...

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

845
A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

NMR Spectrometers: Resolution and Error Correction

729
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

Area of Science:

  • Quantum Physics
  • Spectroscopy
  • Materials Science

Background:

  • Electron spin resonance (ESR) spectroscopy is vital for characterizing paramagnetic impurities but provides only ensemble-averaged data due to low signal-to-noise.
  • Existing single-spin detection methods are often system-specific or limited to very small detection volumes, posing a challenge for practical applications.

Purpose of the Study:

  • To demonstrate a novel method for single-electron magnetic resonance detection.
  • To overcome the limitations of traditional ESR and existing single-spin techniques.

Main Methods:

  • Utilized spin fluorescence detection with a microwave photon counter at millikelvin temperatures.
  • Coupled individual paramagnetic erbium ions in a scheelite crystal to a high-quality-factor planar superconducting resonator to enhance radiative decay rates.

Main Results:

  • Achieved single-electron magnetic resonance with a signal-to-noise ratio of 1.9 in one second integration time.
  • Observed fluorescence signal anti-bunching, confirming detection of individual emitters.
  • Measured coherence times up to 3 milliseconds, limited by spin radiative lifetime.

Conclusions:

  • The developed method enables single-spin detection with potential applications in magnetic resonance and quantum computing.
  • This technique allows for single-spin detection in a significantly larger volume (approx. 10 μm³) compared to existing methods.
  • The approach is adaptable to various paramagnetic species with suitable relaxation times.
