Description
The excited state dynamics of o-dichlorobenzene has been studied by femtosecond time-resolved photoelectron imaging. The lifetime of the first excited state S1 of o-dichlorobenzene was determined to be 482 ± 10 ps. Field-free nonadiabatic alignment of the o-dichlorobenzene on the first excited state S1 (with an asymmetry parameter k = 0.153) by a femtosecond laser pulse was observed via time-resolved photoelectron angular distributions. Rotational wave packet revivals on the S1 state of the typical asymmetric molecule o-dichlorobenzene at 296 ps has been measured.
