Zeke Photoelectron Spectroscopy as a Probe of Dissociative States

Abstract

During the past decade zero kinetic energy photoelectron spectroscopy (ZEKE-PES)1 has become one of the most important techniques for gas-phase studies of molecular ions and ionic complexes. Compared to conventional photoelectron techniques a resolution enhancement by 2 to 3 orders has been achieved and even the rotational structure of larger polyatomic ions can be resolved.2
