As revealed from Eqs. (1) and (2), or their candid forms (4) and (5), the longitudinal relaxation is determined by the spectral densities in the order of o>h toc, whereas the transverse relaxation involves the contribution from the zero frequency component Jo(0). In the case of solid matter, tc is generally very long. Hence, the transverse relaxation is predominantly determined by the zero frequency component Jo(0). In Eq. (5), for example, the zero frequency term (the first term) dominates the other terms that are reciprocally proportional to Tc for co2x2 1. Tic increases as xc increases (i.e. as the material under consideration becomes solider), whereas T2c decreases infinitely as xc increases. For example, Tic is generally in an order of several tens several hundreds of seconds for the crystalline component and in an order of a few tenths of a second for rubbery components of polymers. On the other hand, T2c is of an order of a few tens of microseconds for the crystalline or glassy component and a few milliseconds for the rubbery component of polymers. In this work, Tic and T2c are used for characterizing different components in crystalline polymers.

Assisted-ion-transfer reactions were pioneered by Koryta [2,151] who, back in 1979, demonstrated the concept of an ion transfer assisted or facilitated by the presence of a ligand or ionophore in the organic phase, first of potassium, facilitated by di-benzo-18-crown-6, and then of sodium by nonactin, a macrotetrolide antibiotic. From a mechanistic point of view, we can classify assisted ion transfer in four different categories as proposed by Shao et al. [152] and as illustrated in Figure 1.15, where ACT stands for Aqueous Complexation followed by Transfer, TOC for Transfer to the Organic phase followed by Complexation, TIC for Transfer by Interfacial Complexation, and TID for Transfer by Interfadal Dissociation.
