Abstract:

There is claimed a liq. medium capable of giving a resolved diffusion ordered NMR spectra of mixts. of compds. that is both stable and less susceptible to magnetic susceptibility effects. The present invention relates to homogeneous liq. systems substantially 1H- NMR inactive and/or devoid of protons and are capable of enhancing the diffusion sepn. of a mixt., wherein said system is substantially devoid of at least one NMR active nucleus present in said mixt. The invention further discloses methods of using said homogeneous liq. systems for enhancing the diffusion sepn. of a mixt. and/or generating a diffusion ordered spectrum of a mixt. and/or minimizing the peak width in a liq. state diffusion ordered spectrum of a mixt.
