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