Time dependence of the NMR line shape for systems with chemical exchange in a zero saturation limit

Abstract

An expression has been derived for the time dependence of the NMR line shape for systems with many-site chemical exchange in the absence of spin-spin coupling, in a zero saturation limit. The dynamics of variation of the NMR line shape with time is considered in detail for the case of two-site chemical exchange. Mathematica programs have been designed for numerical simulation of the NMR spectra of chemical exchange systems. The analytical expressions obtained are useful for NMR line shape simulations for systems with photoinduced chemical exchange.
