Time Resolved Spectroscopy with Synchrotron Radiation in the Vacuum Ultraviolet

Abstract

The pulsed nature of synchrotron radiation permits time resolved spectroscopy in the VUV spectral range. In the foreground of discussion is the use of time resolved techniques in fluorescence spectroscopy. The time constants presently accessible extend from the ps to the ms regime, over nearly nine orders of magnitude. The experimental techniques which fit best to the properties of the excitation source, as well as an advanced experimental set-up for time resolved fluorescence spectroscopy, are described. Various results are presented demonstrating the unique possibilities for time resolved VUV spectroscopy offered by synchrotron radiation excitation.
