Abstract: It is well known that NMR spectra are affected by chemical exchange between states, in which the spectra unperturbed by exchange represent single Lorentz lines or multiples of Lorentz lines [1-3]. Of specific interest also is investigation of chemical exchange in systems where the spectrum of at least one of the states consists of nonuniformly broadened lines. Such a situation arises, particularly, during observation of the NMR of molecules sorbed on a surface and capable of migrating between various adsorption sites [4, 5]. On account of the low mobility of chemisorbed molecules their NMR spectra represent nonuniformly broadened lines, whereas at sites of physical adsorption fast exchange and effective rotation of the molecules average the NMR spectrum into a line of Lorentz form.
