Spin decoupling, chemical exchange

S-spin zero-quantum line shape is sufficiently broadened to allow S-spin polarization transfer. The broadening of the zero-quantum line can also be caused by chemical exchange ( motionally-driven spin diffusion ) [15, 18]. In a different approach one decouples the protons and removes the chemical-... [Pg.91]

The time-consuming 2D experiment can be replaced by ID selective inver-sion-recovery/saturation-transfer experiments [119]. Its application to study the heterogeneity of PS/PVME is mentioned afterwards (see Section 10.3.1.1). Furthermore, Campbell and VanderHart [109] showed that the selective techniques under multiple-pulse homonuclear decoupling are not necessary. They realized that at certain t value in a 2D exchange NMR experiment, polarization gradient necessary for spin diffusion can be achieved by the chemical shift difference. The optimum preparation period for the ID analogue of the 2D exchange NMR experiment was discussed. [Pg.380]
