Dynamics of multiple quantum coherences in dipole-coupling spins in solid Academic Article uri icon

abstract

  • A perturbation method deals with dipolar coupling spins in solids is presented. As example of application the method, the multiple-quantum coherence dynamics in clusters of a linear chain of four nuclear spins and a ring of six spins coupled by dipole–dipole interaction are considered. The calculated 0 Q and 2 Q intensities in a linear chain of four nuclear spins and 6 Q intensity in a ring of six spins vs. the duration of the preparation period agree well with the exact solutions (for linear chain of four nuclear spins) and simulation data (for linear chain of four nuclear spins and a ring of six spin).
