 Abstract: This paper deals with the theoretical foundation of proton magic-angle-spinning rotating-frame relaxation (R1ρ) and establishes the range of validity and accuracy of the presented approach to describe low-amplitude microsecond timescale motion in the solid state. Beside heteronuclear dipolar and chemical shift anisotropy interactions, a major source of relaxation for protons is the homonuclear dipolar interaction. For this latter relaxation process no general analytical equation has been published until now which would describe the R1ρ relaxation at any spinning-speed, spin-lock field, or tilt-angle. To validate the derived equations we compared the analytical relaxation rates obtained by solving the master equation within the framework of Redfield theory with numerically simulated relaxation rates. We found that for small opening angles (~10°) the relaxation rates obtained with stochastic Liouville simulations agree well with the analytical Redfield relaxation rates for a large range of motional correlation times. However, deviations around the rotary-resonance conditions highlight the fact that Redfield treatment of the solid-state relaxation rates can only provide qualitative insights into the microsecond timescale motion.
