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
The 13C resonances for all protonated carbons have been observed and assigned for the free base esters derived from the following natural products: heme d, the prosthetic group of the bacterial cytochrome oxidase cytochrome d; heme d,, the prosthetic group of the dissimilatory nitrite reductase cyto
