Abstract
The orientational distribution in partially ordered solids, drawn polymers, etc. is related with NMR and ESR line shapes governed by anisotropic shift, dipolar, or quadrupolar couplings. In principle, the theory yields the complete orientational distribution by numerical deconvolution or spectral fitting procedures. Furthermore, the line shape can be decomposed into subspectra that correspond to the moments of the orientational distribution. The theory is applied to 2D‐NMR line shapes in partially ordered solid benzene, and to ESR nitroxide spin label spectra.Keywords
