Ionization energy studies for ozone and OCIO monomers and dimers

Abstract

Electron impact ionization cross sections for ozone and chlorine dioxide (OClO) monomers and dimers were analyzed using high resolution electron impact apparatus. The quadrupole mass spectrometry measurements showed the bond energy of the ozone ionic dimer to be very high. The results show that the ion produced by ionization of the ozone dimer is no longer a conventional dimer ion where the two monomer units are present.
