Schematic depiction of the variance of the phase, ⟨ϕ2⟩=−2logC(t) , as a function of the measurement duration t , for both Ramsey/DEER (purple) and spin echo (orange). The labelled slopes indicate the predicted stretch powers in both the early-time ballistic regime and the late-time random-walk regime (Table 1 ). The cross-over occurs at the correlation time, τ c .
