- Аннотация: Multiple quantum (MQ) NMR dynamics in an inhomogeneous spin chain, where the distances between the various pairs of neighboring spins can be different, has been studied in the approximation of nearest-neighbor dipole–dipole interaction (DDI). Though the fermion spectrum after performing the Jordan-Wigner transformation is not known, this article shows that the MQ NMR spectrum consists of MQ coherences of orders 0 and ±2 only, and their intensities are determined by the system’s fermion spectrum. As an example application of the theory developed, we calculate MQ NMR spectra of uniform, alternated and doubly alternated (with three different dipolar coupling constants) spin chains.
