Abstract

Cross‐polarization (CP) magic angle spinning (MAS) ^6^Li{^1^H} spectra were acquired for three different inorganic lithium compounds. Spectra with a good signal‐to‐noise ratio can be obtained in reasonable times. The poorer signal‐to‐noise ratios shown by spectra acquired in the same experimental time by means of a single pulse experiment are explained by the longer values of T~1~(^6^Li) in comparison with T~1~(^1^H). The determination of these values allows the acquisition parameters to be optimized. In particular, the optimum experimental conditions are discussed, taking into account the pulse delay, the number of transients and the total time of the experiment. Finally, a standard for ^6^Li^1^H CP matching is proposed.

The effect of an offset term in the cross-polarization (CP) Hamiltonian of a heteronuclear spin-12 pair due to off-resonant radio frequency (rf) irradiation and/or chemical shift anisotropy on one of the rf channels is investigated. Analytical solutions, simulations, and experimental results are pre

Theoretical models for motionally driven spin diffusion are compared and applied to spins S = (1/2) and S = 1. Their predictions are quantitatively corroborated by experiments on a single crystal of deuterated biphenyl. In this system, a molecular flip process drives spin diffusion and makes it stro
