Abstract

In this contribution we will report on recent experiments aimed at studying the spectroscopy and the dynamics of state selected molecular ions. One of the major sources for kinetic and energetic information on unimolecular reactions of ions has been the one photon ionization of molecules with consecutive reaction. In this large field the most direct results emerged from investigating energy and/or state selected ions. In those experiments which do not inherently produce state selected ions the photoelectron photoion coincidence (PEPICO) technique [1] has to be applied. Typically these experiments have been performed at a resolution of about 30 meV (240 cm− l) limited by the contribution from the photons and the electron energy. Applying this technique we have recently studied the J dependence of the dissociation energy Eo(J) [2,3]. It was at the same time the advantage and the limitation of this experiment that it did not require J selectivity but simply used the variation of the rotational temperature.
