Latest Patents

Anne Lesage holds a patent for a method to improve the resolution of two-dimensional heteronuclear correlation spectra in solid-state NMR. This patent describes a new two-dimensional NMR carbon-proton chemical shift correlation experiment, known as the MAS-J-HMQC experiment, which is specifically designed for rotating solids. The magnetization transfer utilized in this method is based on scalar heteronuclear J couplings. The resulting 2D map provides through-bond chemical shift correlations between directly bonded proton-carbon pairs, similar to high-resolution liquid state experiments. The efficiency and selectivity of the J coupling transfer method surpass those based on heteronuclear dipolar couplings. This experiment operates at high magic angle spinning (MAS) rates, allowing for the unambiguous assignment of proton resonances. The effectiveness of this method has been demonstrated on several organic compounds.
