摘要：

The title compound, aligned in uniaxially stretched polyethylene (PE) sheets has been investigated by infrared linear dichroism (LD) spectroscopy. It has been possible to observe 38 vibrational transitions and to determine orientation factors for several of the transition moment directions. The only reasonable interpretation of the experimental data is that the observed molecule has C-2v-symmetry and that the compound adopts the symmetrical dienol form when dissolved in PE. The IR LD spectra do not indicate the presence of keto or enol forms, in contrast with the results of previous IR investigations using Nujol mull as the solvent.
