    • We have independently verified by a separate rigid limit simulation that the use of the slow-motional tumbling programs is valid for extracting the rigid limit parameters. We point out that this is further evidence of the limited resolution of cw spectra to dynamics very close to the rigid limit.

    • 0 correspond to values of β≈0.9 which would be inconsistent with the results of other physical techniques, whereas the values of β≈0.6 we obtain for these ESR spectra with the dynamic cage model fits are consistent, as we have shown above.

    • note
    • c is characteristic of the incipient smr, which is actually quite broad. A restricted distribution, covering the incipient smr to deep into the smr would still be a broad superposition and not have the distinctive two-component features seen experimentally, [cf. Fig. 1(b)].
