UV-Vis Spectroscopy: Theory and "How do I know when to use it?"

The video tutorial covers the basics of UV VIS spectroscopy, focusing on the absorption properties of various molecules. It explains the significance of double bonds and conjugation in determining a molecule's ability to absorb UV light. The tutorial also delves into electron transitions, particularly π to π star transitions, and their role in spectroscopy. Additionally, it outlines the UV VIS spectroscopy technique, including the use of a cuvet and light source, and discusses the relationship between energy and wavelength. The video concludes with potential applications in biochemistry, such as identifying proteins and nucleic acids.
