4448 L23 Atomic Spectroscopy, Spin-Orbit Coupling, and the Expansion of the Universe 2024

DW demonstrates the differences between the continuum spectrum of a tungsten filament lamp and the mercury vapor fluorescent light. He discusses the line spectrum fingerprint for each element, and how we use these fingerprints to determine the distances to stars and galaxies in our universe.
Background
These are videos of Dr. Williams’ CHEM Physical Chemistry Lectures at Sam Houston State University. They are provided for your benefit for studying if you are a student or for your curiosity if you are not a student.
This course is the Quantum Mechanics and Spectroscopy Course. DW teaches this course in a unique way with emphasis on the spectroscopy of the 1D Particle in a Box system and the early introduction of symmetry for interpreting spectroscopic results.
