Kinetic isotope effects for fast deuterium and proton exchange rates

By monitoring the effect of deuterium decoupling on the decay of transverse ¹⁵N magnetization in D–¹⁵N spin pairs during multiple-refocusing echo sequences, we have determined fast D–D exchange rates k_D and compared them with fast H–H exchange rates k_H in tryptophan to determine the kinetic isotope effect as a function of pH and temperature.
