NMR of Proteins

-enhancement depends on 1/r6, where r is the internuclear distance-thus, the effect is limited to distances of approximately 5Å or less • This provides a means to determine if any two protons in a protein are < 5Å apart • The basic experiment used for proteins is called a NOESY 90 90 90 2D NOESY t 1 τ m t 2 The Nuclear Overhauser Effect
