Part 2. Spectroscopy. Fundamentals and Instrumentation.

Topic Lecture Notes and Reference Materials
Days
Reading/Study Assignment (SHN = Skoog, Holler, Nieman, 5e)
2A. Fundamentals of Spectroscopy

Fundamental Concepts in Spectroscopy. Electromagnetic spectrum and chemical analysis. Absorption and emission in atomic and molecular systems. Wave properties and quantum-mechanical properties of electromagnetic radiation. Absorption, emission, and concentration.

Many of these topics have been introduced earlier in physics and physical chemistry. Lecture discussion will focus on principles of diffraction, relaxation processes for excited atoms and molecules, and quantitative relationships between absorption or emission and concentration.
