Measurement of relative atomic transition probabilities using flame atomic absorption spectroscopy

A simple and straight forward technique was developed to measure relative atomic transition probabilities using flame atomic absorption spectroscopy. Relative atomic transition probabilities for Co, Cr, Cu, Fe, Mn, Mo, Ni, Sc, Ag, Na and Ti were determined. Atomic absorption measurements in air-acetylene and nitrous-oxide acetylene flames using both line emission and continuum excitation sources were employed. A comprehensive discussion and critical evaluation of relative atomic transition probabilities for this work and others of comparable scope and design is included. The effect of the overall absorption line profile including hyperfine structure broadening is discussed for the line emission source absorption data.
