    • We stress that this random walk is merely a useful analogy to manipulate the Kronecker symbols in (24). It has no relation to the physical diffusion of spins in a slab geometry.

    • The efficiency and accuracy of this computation will, of course, depend on the temporal profile f (t). For instance, if the content of f (t) is too narrow (as in the case of Stejskal-Tanner narrow pulses), one needs to use specific distributions of moments t1, , tn to perform trials.

    • The integral representation (38) for 1 can be rigorously derived from its definition (18). In contrast, this definition is in general not applicable to with <1. The coefficient 32 is formally defined by series expansion (37) of the second moment as p→0; see Ref. 15 for details.

    • The numerical implementation of the MCF approach to compute the signal attenuation in a linear magnetic field gradient was thoroughly discussed in Ref. 15. In this particular case, the MCF numerical technique is similar to the stepwise gradient approximation by Barzykin (Refs. 43 44).

    • Although difficult to demonstrate rigorously, it is natural to assume that the next significant contribution after the second moment would be given by the fourth moment (n=2).

    • To better fit the signal as a function of q, we slightly modified the relation (48) by introducing an adjustable coefficient a0, Eex [- a0 (π 2) (pq) 12]. We took a0 equal to 1.13, 1.00, and 0.60 for p=0.1, p=1, and p=10, respectively. This minor modification may be related to some -dependent corrections to the asymptotic behavior (48).
