Atomic Absorption Spectroscopy: Radiation and Light Sources

Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

π Electron Effects on Chemical Shift: Overview

An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0, resulting in...

Atomic Emission Spectroscopy: Lab

AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

Atomic Emission Spectroscopy: Overview

Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the aerosol...
Atomic Emission Spectroscopy: Instrumentation01:22

Atomic Emission Spectroscopy: Instrumentation

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.

Area of Science:

  • Atomic and Molecular Physics
  • Quantum Chemistry
  • Laser-Matter Interactions

Background:

  • Interatomic Coulombic decay (ICD) is a key process in excited atomic clusters.
  • Existing methods often rely on single-photon absorption, which can be inefficient.
  • High laser intensities can lead to competing ionization processes.

Purpose of the Study:

  • To propose and demonstrate a more efficient method for inducing ICD using multiphoton absorption.
  • To investigate the production of low-energy ICD electrons and Ne(+) pairs in Ne(2).
  • To analyze the influence of laser intensity and pulse duration on ICD and ionization processes.

Main Methods:

  • Theoretical calculations for Ne(2) clusters.
  • Simulation of multiphoton absorption processes.
  • Analysis of electron spectra and ion pair production.
  • Modeling of time-delayed measurements.

Main Results:

  • Multiphoton absorption is significantly more efficient for ICD than single-photon absorption in Ne(2).
  • Low-energy ICD electrons and Ne(+) pairs are produced, with yields dependent on laser parameters.
  • Successive ionization becomes competitive at higher laser intensities, leading to interfering electron signals.
  • Time-delayed measurements can distinguish ICD contributions from ionization.

Conclusions:

  • Multiphoton absorption offers a superior pathway for studying ICD in atomic systems.
  • Laser intensity and pulse duration critically influence the dynamics of ICD and ionization.
  • Time-resolved detection is a viable strategy for isolating ICD signals in complex laser-driven environments.
