High-resolution one and two photon excitation spectra of trans,trans-1,3,5,7-octatetraene

Article abstract of DOI:10.1063/1.439802

One and two photon excitation spectra for the lowest energy singlet transition (2¹A_g <*> 1¹A_g) of trans,trans-1,3,5,7-octatetraene in n-octane at 4.2 K(0-0 at 28 561 cm^-1) have been measured and analyzed.The one photon spectrum is found to be vibronically induced while the two photon spectrum is electronically allowed.The contribution of the higher lying 1¹B_u <*> 1¹A_g transition (0-0 at approximately 32 100 cm^-1) to the observed two photon excitation spectrum is found to be negligible allowing vibrational overtones of the 2¹A_g <*> 1¹A_gsystem to be observed.On the bases of frequency, intensity, and one or two photon allowedness, 128 measured lines are assigned as combination of 4 antisymmetric and 11 symmetric normal modes.
