## Measurement and assignment of the i.r. and Raman spectra of trans,transand c&tram-2,4hexadienes were carried out. The normal coordinate analyses of these two isomers were done to obtain a force field transferable to 1,4-diphenyl-traqtrans-1,3-butadiene and transand cis-polyacetylenes.
## Abstract The He(Ia) photoelectron (PE) spectra of the (__E,E__)β, (__E,Z__)β and (__Z,Z__)βisomers of the title compound have been recorded to obtain information about their conformation in the gas phase. For a valid correlation with the PE data of other dienes it is necessary to take the potent
