Spectroscopy: Light and Molecules

This lecture covers the principles of Spectroscopy, including Optical Rotatory Dispersion (ORD) and Ellipticity (Circular Dichroism). It explains how these techniques measure the interaction of light with chiral molecules, providing insights into their structure and properties. The lecture also delves into Circular Dichroism (CD) and Raman Spectroscopy, detailing how they analyze the differential absorption of left and right circularly polarized light. Additionally, it explores the use of FTIR and Raman Spectroscopy in characterizing samples, showcasing their applications in various fields such as cultural heritage. The Bohr Model of the atom and the concept of atomic isotopes are also discussed, along with the fascinating Uranium Fission Chain Reaction and its energy implications.
