Spectroscopy Based on Absorption

Spectroscopy Based on Absorption

Historically, the first spectroscopic studies involved characterizing the emission of visible light from the sun, from flames, and from salts added to flames. Our survey of spectroscopy, however, begins with absorption because it is the more important technique in modern analytical spectroscopy.

1. Absorbance of Electromagnetic Radiation

2.Transmittance and Absorbance

3. Absorbance and Concentration: Beer’s Law

4. Beer’s Law and Multicomponent Samples

5. Limitations to Beer’s Law
