For the first three ionized states of ozone the ordering of <SUP>2</SUP>A<SUB>1</SUB>, <SUP>2</SUP>B<SUB>2</SUB> and <SUP>2</SUP>A<SUB>2</SUB> states has so far been controversial both experimentally and theoretically. The present work establishes assignment of the <SUP>2</SUP>A<SUB>2</SUB> state by using the characteristic of electron energy dependence of an asymmetry parameter (β) of photoelectron angular distribution measured with NeI, HeI, and NeII resonance radiation. From measurements of photoelectron spectra of ozone with NeI, HeI, and HeII radiation, we newly find that two bands centered at 16.50 and 17.6 eV exhibit vibrational structures with the spacings of about 850 and about 1000 cm<SUP>−1</SUP>, respectively. Furthermore abnormally weak bands are also confirmed at 22.7, 24.1, and 26.8 eV in the Hell spectrum.
