摘要：

In the present work, utility of diffusion-ordered two-dimensional NMR spectroscopy (DOSY) has been demonstrated to analyse and assign the crowded NMR spectra of mixtures of hydrocarbons using H-1- and C-13-detected DOSY experiments. For the first time, DOSY spectrum of a petroleum aromatic fraction is shown and assessed to illustrate the future applications of the technique for the analysis of such complex and heterogeneous molecular mixtures.
