Exchange(intermediate, fast, slow, chemical and conformational) :Exchange is a kinetic process between two(or more) states that is characterized by a rate constant. In NMR [nuclear magnetic resonance] spectroscopy, exchange is classified into fast, intermediate and slow depending on the size of the rate constant with respect to chemical shift(which is measured in the same units(Hz) as the rate constant). In the fast exchange regime, the rate is much larger than the difference in chemical shift between the two states and the NMR signal will be at the weighted average position of the two states. In slow exchange, signals for both states are observable and the intensities are proportional to the populations of the two states. In intermediate exchange, the transition between the signals seen for slow and fast exchange takes place, resulting in very broad and often non-observable signals. 1, record 1, English, - slow%20exchange
