Figure 5.

a) The decay of the long-lived coherence (LLC) involving the two protons HI and HS of glycine in L-Ala-Gly is affected by the presence of 2.5 mM TEMPO (TLLC=1.43 s). b) After addition of 30 mM sodium ascorbate, the lifetime (TLLC=3.82 s) is extended by a factor of 2.7. Both signals were measured at T=296 K and B0=7.05 T without DNP and fitted with mono-exponential decays multiplied by a sine function. The modulation arises from the scalar coupling constant J=−17.242 Hz.
