Solid-state C variable-amplitude cross polarization magic-angle spinning (VACP/MAS) nuclear magnetic resonance (NMR) spectra were acquired for the sorbitol samples. Proton decoupling was achieved by a two-pulse phase modulation (TPPM) sequence. Identical C spectra were measured for the y-form sorbitol samples, and a representative spectrum is shown in Figure 9. 

The application of nuclear magnetic resonance (NMR) spectroscopy to polymer systems has contributed to significant advances in understanding of their structure and dynamical properties at the molecular level. From the analytical point of view, NMR spectroscopy is particularly suitable for a determination of the polymer structure by direct observation of the protons and carbons in different structural moieties. However, until the mid-1970s the application of this technique was limited to polymer solutions and to some elastomers in the solid state with a relatively high degree of the molecular mobility which allows the observation of the motionally narrowed absorption signals. 

Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR) also had some success in determining proton positions. Side-band analysis from solid-state H NMR was used to determine proton positions [19, 20] in ZSM-5 type zeolites. 

In support of this idea, both 6 and 7 showed binding to 1.3.5-trinitrobenzene (TNB). in the solid state and in solution, as evidenced by shifts observed in the proton nuclear magnetic resonance (NMR) spectra of mixtures of...
