The absorption spectrum of the pyrene excimer in a single crystal has been measured. The spectrum is similar to that obtained in solution. The polarization of the absorption peaks in the crystal was found to be similar to that of the excimer fluorescence emission. The overlap between the excimeric e
An absorption spectrum attributable to the transition from the first excited singlet state to higher singlet states (S' Q--S transition) of pgrene in soIution has been observed by the flash method.

An inversion scheme to obtain excited-state potential energy surfaces from experimental absorption spectra is presented. The scheme is based on simulating the quantum dynamical processes with high accuracy. A modification of the simulation enables analysis of regions in the potential which the absor
