Physical Chemistry 2, Part 33:  Multiplicity, Angular Momentum, and Term Symbols
Channel: StrangerThanFic
Date: 2022-07-08

In today's video, we'll look at the two types of angular momentum that electrons possess:  intrinsic angular momentum (aka, spin) and orbital angular momentum.  We'll see how these lead atoms to have a variety of electronic energy states with different multiplicities, and how these affect the spectroscopic properties of the atom.  Finally, we'll see how all this information can be summarized in a term symbol -- this part is one of the trickiest concepts we'll cover, so it takes some explaining.  All in all, it makes for my longest video, but it's worth it if you want to understand the spectroscopic literature!
