✦ Synopsis
Cross-correlation between proton chemical shift anisotropy and proton-proton dipolar interactions is shown to be an important relaxation mechanism. Cross-correlation leads to a partial converaion of Zeeman order into longitudinal two-spin order. The build-up of longitudinal two-spin order can be observed selectively by means of a novel experiment that combines double-quantum filtration with two-dimensional nuclear Overhauser effect spectroscopy (DQF-NOESY).
