Magnetic resonance is the most widely applied tool for garnering information about structure and motions of molecules and materials. The unique power of Nuclear Magnetic Resonance [NMR] (and Electron Paramagnetic Resonance [EPR]) is related to the weakness of the Hamiltonians involved, and the corresponding long lifetimes of non-equilibrium states (phase coherence). I will focus my talk on the aspects of magnetic resonance that allow us to determine molecular structure and motion using a semi-classical approach. I will discuss 2nd-rank tensors and anisotropy, the density matrix, and auto-correlation functions. I will cite a few examples from my students' work over the years.
