A depolarization scheme for suppressing rigid protonatcd carbon-l 3 signals in CP MAS NMR is presented. The principle underlying the new scheme is not proton-carbon dipolar dephasing, but the depolarization of carbon-l 3. Because the carbon-13 magnetization is always locked by irradiation before the

It is demonstrated that inversion-recovery cross polarization methods may be successfully employed to detect non-protonated resonances in high-resolution solid-state NMR. By incorporating a short inverse polarization ttme ( zz I50 us) after the normal cross polarization period, the resonances of car
We describe a new multiple-pulse sequence (FLOPSY-8) for broadband homonuclear cross-polarization and compare it both theoretically and experimentally with the previous state of the art. FLOPSY-8 offers significant improvements in cross-polarization effkiency compared with the best alternative, and
