Structural biology

For someone who knows structural biology, NMR stands for nuclear magnetic resonance. It is a spectroscopic technique to study the structures and dynamics of molecules at atomic resolution. The molecules can be small organic molecules, or can be macromolecules or biomolecules, such as proteins and nucleic acids. NMR can study samples in both solution state and solid state. I have some expertise on biomolecular solution state NMR. I would like to write down some notes about this topic.
