โœฆ Synopsis

The absorption and polarization spectra from the first excited singlet state of pyrene and the absorption spectrum of the pyrene excimer are presented. These results were obtained by laser flash spectroscopy using a frequency doul bled ruby laser pulse of 6 nanoseconds halfwidth.

A qualitative preliminary assignment of the bands is given.

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
