Introduction to Atomic Spectroscopy

  1. Be able to draw and explain atomic energy level diagrams. Be able to indicate atomic absorption and atomic emission (fluorescence) on the diagram, AES web page, (History & Theory, energy level diagrams).
  2. Understand phenomena contributing to atomic spectral line width, i.e. Doppler and pressure broadening.

  3. Be able to explain the effects of temperature on atomic spectra, i.e. Boltzmann equation.

  4. Be able to explain the functionality of an atomizer and be able to describe how samples (solid and aqueous) are prepared for eventual atomization. (Introduction of analyte (electrothermal vaporization and nebulizers)).
