The direct experimental determination of a dipole–dipole cross-correlation spectral density

Abstract

A novel method for ascertaining certain dipolar cross-correlation spectral densities is described in detail. This method is based upon the inherent simplicity associated with the perturbation-initial-response characteristics of various multiplet or multispin magnetizations. Furthermore, it is demonstrated that suitable multipulse sampling sequences can be devised which effectively sequester conventional nuclear magnetization and, hence, facilitate the study of multispin magnetization. The outlined methodology is applied to determine a three-spin cross-correlation spectral density for an adamantyl methylene spin grouping.
