## Abstract Diffusionโordered spectroscopy (DOSY) is a powerful technique for mixture analysis, but in its basic form it cannot separate the component spectra for species with very similar diffusion coefficients. It has been recently demonstrated that the component spectra of a mixture of isomers w

The feasibility of using diusion-ordered NMR spectroscopy (DOSY) as a useful probe to qualitatively understand the relative strength of hydrogen bonds between various components in a mixture and a ligand in non-aqueous solutions has been demonstrated. 1 H-detected DOSY and 31 P-detected DOSY were us
## Abstract Diffusionโordered NMR spectroscopy resolves mixture components on the basis of differences in their respective diffusion coefficients or molecular sizes. However, when components have nearโidentical diffusion coefficients, they are not resolved in the diffusion dimension of a diffusionโ
