Laser photoelectron spectroscopy: mixed traits of excited states

Abstract

Laser photoelectron spectroscopy possesses unique properties for elucidating the electronic structure of excited states of small- and medium-sized molecules. The method has significantly contributed to the understanding of excited-state spectroscopy and dynamics of a large variety of chemically relevant molecules. Illustrative examples will be discussed in which the often dominant role of superexcited states is highlighted, and in which attention is focused on recent research concerned with the direct experimental observation of configuration interaction.
