High-resolution photoelectron spectrum of ozone

The photoelectron spectra of ozone have been recorded and the first three electronic band systems reassigned on the basis of observed vibrational structure and calculations reported in the literature. The systems X?,Ã, and B? at 12.75, 13.03, and 13.57 eV are assigned as ²A₁, ²A₂, and ²B₂, respectively.
