摘要: Rotationally resolved S1−S0 fluorescence excitation spectra of ethylbenzene, two conformers n-propylbenzene, and n-butylbenzene have been observed assigned. The data obtained provide information about the equilibrium properties each molecule, including their geometries in states, electronic distributions, dynamical behavior following absorption light. Trans structures are found to S1 states that 1Lb character with relatively long lifetimes. Gauche mixed (1Lb/1La) short Possible reasons for these differences discussed.
