✦ Synopsis

H NMR spectra of some mmllmolecules oriented in stretched polyethylene rods have been recorded. The band splitting due to direct dipole-dipole couplings is obtained and the corresponding orientation parameters are shown as a function of the draw ratio of the polymer and the temperature. This method is compared to that of using liquid crystals as the orienting solvent.

Triplet-state ESR spectra show that when the aromatic molecules anthracene, anthracene-d,,,, terphenyl, and acridine are dissolved m stretched, low-density polyethylene films, a fraction of these solute molecules become oriented with their X axis along the stretch direction but with their XY planes
