Abstract

An improved constant time gradient HSQC-iDOSY pulse sequence is presented, and the corresponding form of the Stejskal-Tanner equation is derived. The pulse sequence is particularly well suited to the problem of analysing mixtures of chemically cognate species, where the high spectral resolution afforded by 1H-13C correlation methods is needed for DOSY experiments to give good diffusion resolution. Its use is illustrated for amixture of rutin and its aglycone quercetin. © 2009 John Wiley & Sons, Ltd.
