We present calculations on the geometry of the first 'B. excited state in polyene chains ranging in length from 5 to 29 double bonds. Calculations are performed in the framework of a Hiickel Hamiltonian with bond-length-dependent transfer integrals and with o-bond compressibility and use the paramet
The triplet state Raman spectra of C6O and C7o in toluene were obtained using the pump/probe technique. For C6o, new bands at 1461 and 1475 cm-1 appeared around 1470 cm-1 in the triplet state. The Raman peaks at 1448 and 1368 cm-1 for C7o shifted to lower frequencies due to the increase in antibondi
