When a spin-12 nucleus is dipolar coupled to a spin-1 nucleus, the spectrum of the spin-12 nucleus can be split into an asymmetric doublet in magic-angle spinning experiments. When the spin-12 nucleus is 1 3 C and the spin-1 nucleus is 2 H there is also the possibility of this splitting being modified by the indirect (J) coupling. 1 3 C- 2 H residual dipolar couplings are seen because of the large full dipolar coupling of the nucleus pair. However, this has implications on the spinning speed used in the CP/MAS NMR experiment and the intensities of the isotropic 1 3 C dipolar coupled to 2 H. The calculation of side band intensities for slow spinning when the dipolar, quadrupolar and chemical shift tensors are axially symmetric and coaxial is discussed.
