The dynamic NMR (DNMR) deals with different techniques for rate constant determination for different chemical processes. The complete band shape analysis is applicable to the study of processes occurring with rate constants between 1 and 104 s-1. The measurements of relaxation times are useful for faster processes with rate constants of the order of 102-106 s-1 and the spin-saturation technique can be applied for slower processes (k = 0,1-100 s-1. Kinetic measurements by EXSY experiment are applicable for rate constants between 10-2 and 102 s-1. The advantages and pitfalls of every method were discussed.
