An extension of cross-depolarization experiment: Two-dimensional NMR powder pattern

A formal description and a numerical simulation of a new depolarization two-dimensional pulse sequence, based on the standard cross-polarization method, have been given. The proposed sequence can be used for obtaining chemical shift-heteronuclear dipolar correlated spectra. The depolarization ofS-sp...

Summary:A formal description and a numerical simulation of a new depolarization two-dimensional pulse sequence, based on the standard cross-polarization method, have been given. The proposed sequence can be used for obtaining chemical shift-heteronuclear dipolar correlated spectra. The depolarization ofS-spin magnetization at the magic angle during evolution time t1 is used to introduce the heteronuclear dipolar interaction as a modulation of the chemical shift domain t2. This could be used for obtaining geometrical orientation and motional information in solids with strong heteronuclear dipolar interaction.
