| Outline of Final Research Achievements |
Relaxation dynamics of 1,3-pentadiene(PD) and 2,5-dimethyl-2,4-hexadiene(DH) were investigated by time-resolved photoelectron spectroscopy to elucidate the effects of the steric hinderence or the mass by the methyl groups on the relaxation dynamics of the conjugated dienes.
Our theoretical calculation reveals that the molecular structure of DH at a conical intersection is totally different from those of BD and PD, which might be attributable to the steric hinderence. Upon returning to the ground state, the stimulated vibrational modes in DH and PD are different because of the different structure at the conical intersections. This difference appears in the photoelectron specra.
