Sur le spectre électronique de l'ion ozonide, 03−

Abstract

Potassium ozonide dissolved in liquid ammonia absorbs fairly strongly in the u.v. from 300 nm, in addition to the strong band in the violet–blue. Previous conflicting results were due to interference of other species, such as O3, O2−, and HO2, which also absorb in that region. The irregular spacing of the maxima in the visible band points to some interference of a second vibrational mode of the upper state.
