Absorption spectra of α,ω-diphenylhexadecaoctaene and shorter diphenylpolyenes.
Absorption spectrum of α,ω-diphenylhexadecaoctaene has been measured along with those of α,ω-diphenylpolyenes with one to seven double bonds in the polyene chain in carbon tetrachloride at room temperature. Extrapolation of the observed vibrational frequencies in the 1(1)Bu state measured as a function of polyene double bond number provides the CC and CC stretching frequencies of 1520±20 and 1080±20 cm(-1), respectively, for diphenylpolyenes with infinite polyene chain length.
