✦ Synopsis

In the exchange reaction between deuterium and hydride molecules, the consecutive single-step m~hanism is characterized by interactions only between the ith deutero-isomer and the (i f 1) and (i -1) isomers. Rate equations have been set up on this basis and their exact and unique solutions found. This permits the deutero-isomer distribution to be expressed analytically as a function of the time. If the initial state contains only undeuterated hydride or a binomial distribution of isomers, the distribution has been shown to maintain its binomial character to equilibrium.

An application of the analysis to two exemplary cases has been made.

## Abstract In proton nmr, the chemical exchange rates of slowly exchanging labile hydrogens (with lifetimes in the range ∼ 10 msec – ∼ 1 sec) of peptides, proteins, and nucleic acids can be measured in H~2~O by a combination of two separate experiments: (1) the transfer of solvent saturation and (
