— Nanosecond excited state absorption spectra of all‐tram‐l,4‐diphenyl‐l,3‐butadiene (DPB) and a rigid s‐cis DPB analog, 1,4‐diphenyl‐l,3‐cyclopentadiene, were obtained in several hydrocarbon solvents at room temperature and low temperatures. Analysis of the excited state absorption spectra of these two molecules suggests the presence of excited state s‐cis rotamers in DPB at room temperature.
