Abstract
A vector model of the multiplet-selective excitation of spin systems by a three-pulse sequence is considered, and, on this basis, a new two-dimensional exchange NMR spectroscopy technique is suggested. This technique provides means to investigate intramolecular and intermolecular chemical and spin exchanges by observing the dynamic behavior of the multiplet pattern of a nucleus that is scalarwise coupled with the unobservable nucleus undergoing exchange.
