We examine coherent evolution of spin-locked magnetization during magic-angle spinning (MAS), in the context of relaxation experiments designed to probe chemical exchange (rotating-frame relaxation (R<sub>1ρ</sub>)). Coherent evolution is expected in MAS based rotating-frame relaxation decay experiments if matching conditions are met (such as, ω<sub>1</sub> = nω<sub>r</sub>) and if the chemical shielding anisotropy (CSA) is substantial. We show here using numerical simulations and experiments th ...[more]
