The follow-up video on More Advanced Theory can be found here: https://youtu.be/1ZN3MFfd3Hc.
This video discusses the basic theory behind NMR spectrocopy. It is useful for the first year PCAS module, but is important as a reminder for final year Advanced Organic Synthesis and Spectroscopy (before moving on to the more advanced theory).
A great reference for this type of stuff is "A Complete Introduction to Modern NMR Spectroscopy" by Roger S. Macomber.
