SELECTIVE HIGH-RESOLUTION PROTON NMR-SPECTRA IN SOLIDS

A technique is presented where double resonance pulse schemes, which remove both homonuclear and heteronuclear dipolar interactions, have been used to isolate the chemical shift spectrum of specific protons within polycrystalline solids. Proton spectra of Ca(CHO2)2 demonstrate the ability of the scheme to produce undistorted powder patterns, and the selective character of the technique is demonstrated with results from several organic solids and an absorbed system. © 1979.
