Analytical Methods for Atomic Absorption Spectroscopy
www1.lasalle.eduEmission vs. Absorption 3 GENLINFO.DOC, 9/10/96 1:44 PM Emission vs. Absorption All modern Perkin-Elmer atomic absorption instruments are capable of measuring both atomic absorption and atomic emission. It is important for the operator to understand the processes that occur in each technique.

cpb-us-e2.wpmucdn.comabsorption of energy at that frequency. Bond strength is directly related to frequency. In other words, more energy (a higher frequency) is required to vibrate a stronger bond. Because of this relationship, IR spectroscopy is typically used to show the presence of certain bonding types. Bond Type Expected Frequency Range of peak (ω, cm-1 ...
