| Abstract: | Abstract Examination of the Infrare and Raman spectra of cis, cis-dipropenyl ether (which was produced by isomerization of diallyl ether) has produced evidence for strong vibrational coupling between the two double-bonds. This ether has strong bands it 1655 cm?1 in the infrared and at 1691 cm?1 in the Raman. The 1658 cm?1 band in the Raman is about 10 fold less intense than the strong polarised band. Thus it appears reasonable to associate the strong IR and Raman bands with the asymmetric and symmetric vibrations shown. |
