Hyperfine Coupling: Experimental Techniques & Specific Heat

This lecture covers the concept of hyperfine coupling, which describes the interaction between electronic spin and nuclear spin, leading to the splitting of energy levels. The isotropic nature of hyperfine coupling is explored through examples involving spin one half and spin one nuclear spins, demonstrating how the number of lines in the spectrum increases. The lecture also discusses the practical applications of hyperfine coupling in determining the relative positions of magnetic and non-magnetic ions in materials.
