Abstract

We present the photoelectron spectroscopy of the simplest Criegee intermediate, CH₂OO, close to the first ionization energy. Comparison with existing theoretical data yields the experimental adiabatic ionization energy and provides a benchmark for theoretical studies on larger Criegee intermediates, which play an important role in the ozonolysis of alkenes.
