Atomic Emission Spectroscopy: Instrumentation01:22

Atomic Emission Spectroscopy: Instrumentation

1.4K
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers.  Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.

Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

674
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Double Resonance Techniques: Overview

792
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...

Atomic Absorption Spectroscopy: Interference01:25

Atomic Absorption Spectroscopy: Interference

2.1K
Interference leads to systematic error in atomic absorption (AA) measurements by enhancing or diminishing the analytical signal or the background. These interferences can be grouped into three main categories: spectral interference, chemical interference, and physical interference.
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Atomic Nuclei: Larmor Precession Frequency01:11

Atomic Nuclei: Larmor Precession Frequency

3.2K
The earth's gravitational field produces a 'twisting force' perpendicular to the angular momentum of a spinning mass (such as a spinning top) that causes the mass to 'wobble' around the gravitational field axis in a phenomenon called precession. Similarly, the magnetic moment (μ) of a spinning nucleus precesses due to an external magnetic field directed along the z-axis. The precession of the magnetic moment vector about the magnetic field is called Larmor precession,...

Atomic Nuclei: Nuclear Relaxation Processes01:23

Atomic Nuclei: Nuclear Relaxation Processes

1.3K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Spectroscopy

Background:

  • Nuclear resonant scattering of synchrotron radiation by Mössbauer nuclei is a key technique for studying slow dynamics at the interatomic length scale.
  • Existing time-domain interferometry (TDI) setups can be sensitive to external vibrations, limiting measurement accuracy and duration.

Purpose of the Study:

  • To develop and characterize a novel TDI scheme for enhanced efficiency and reduced sensitivity to vibrations.
  • To enable more accurate measurements of slow dynamics over longer timescales.

Main Methods:

  • Development of a new TDI scheme utilizing a nuclear absorber with a two-line energy spectrum combined with a single-line spectrum.
  • Characterization of the experimental setup, including absorbers at rest to minimize external vibrations.
  • Detailed discussion of the model for describing beating patterns in a three-line spectrum system.

Main Results:

  • The new TDI scheme significantly reduces issues from external vibrations as absorbers are stationary, eliminating the need for a velocity transducer.
  • Beating patterns can be measured with satisfactory statistical accuracy and contrast up to 350 ns.
  • Successful demonstration of the scheme's capabilities using the prototypical glass-former ortho-terphenyl.

Conclusions:

  • The developed TDI scheme offers a more robust and efficient method for studying slow dynamics at the interatomic scale.
  • This technique opens new possibilities for investigating the dynamics of materials, particularly in condensed matter systems.
  • The reduced sensitivity to vibrations allows for higher precision measurements over extended time ranges.
