✦ Synopsis

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 oriented randomly to the stretch direction. The fraction of molecules involved in the orientation process is largest for terphenyl.
