✦ Synopsis

The photophysical properties of single a-and a-perylene microcrystals were investigated using femtosecond transient absorption spectroscopy in conjunction with a microscope at 293 K. Formation of dimer cations in respective microcrystals, and the mechanism of exciton-exciton annihilation were analyzed in terms of transient absorption spectra and their decay dynamics as well as crystal structures.

The appearance of coherent artifact signals in transient absorption spectroscopy employing a spectrally integrated detection system is studied. The influence of the detection design on the shape of the observed signal is detailed and the experimentally very important case, in which the shape of the
