Metastable (3-phenyl-2-propynyl)benzenium ions, generated by electron impact induced fragmentation from the appropriately substituted 1,4-dihydrobenzoic acid, react by loss of .CH3 and C6H6.The study of deuterated derivatives reveals that hydrogen/deuterium exchanges involving all hydrogen and deuterium atoms precede the fragmentations.The results suggest a skeletal rearrangement by electrophilic ring-closure reactions giving rise to protonated phenylindene and protonated 9,10-methano-9,10-dihydroanthracene prior to the elimination of C6H6 and .CH3, respectively.A study of isomeric + ions by collision-induced decomposition and by deuterium labelling shows that these ions interconvert by hydrogen migrations and skeletal rearrangements.

The polarized UV absorption spectrum of 1,3-diphenyl-1,2-propadiene (DPA) wasx measured in a stretched polymer film at 101 K, and the polarization directions of the lectronic absorption bands were determined.Pariser-Parr-Pople (PPP) calculations extended
