15N T1, T2 and NOE calculated with SRLS (JDD(ω) was calculated according to eq 10, and JCC(ω) as explained after eq 9) and MF (eq 16) for τm = 5 ns, 11.7 and 18.8 T, as a function of τL = τ0 = 1/6RL (left - SRLS) and corresponding τe = 2τ0/c20 (right – MF). The potential coefficient c20 = 13.2, corresponding to (S20)2 = 0.85, was used.
