NMR observations of orientation in solid polymers

The full spectrum in part (c) was recorded on uniaxially oriented PE film by Nakagawa et al [49], who also did not employ cross-polarization in an attempt to obtain a quantitative spectrum. The narrow resonance labelled I 

By way of examples, we have attempted to illustrate the utility of high resolution NMR spectroscopy to the study of solid polymers. Although we have only presented applications of C NMR, other spin 1/2 nuclei ( N,
