Abstract

We report on ¹³C spin-lattice (R ₁) and spin-spin (R ₂) relaxation rate dependence on magic-angle-spinning (MAS) rate in highly purified synthetic nanodiamonds. Noticeable slowdown of both relaxation processes and reduction of nuclear spin diffusion coefficient D with increasing MAS rate was obtained. This effect is attributed to suppression of nuclear spin diffusion by MAS. We developed a theoretical approach that describes the MAS rate dependence of R ₁, R ₂ and D, allows quantitative analysis of the data and shows good compliance with the experiment.
