Diffusion ordered spectroscopy (DOSY) relies on differences in translation diffusion as a means to separate components in a solution mixture. However, the analysis of spectra of mixtures can be problematic because spectral overlap. It is the aim of this article to propose a pulse sequence and processing method that leads to a complete 2D homodecoupled-DOSY experiment. This experiment offers several advantages that could extend the range of applications to more complex mixtures by achieving important improvements in both signal dispersion and sensitivity.
