ABSTRACT
Chlorine dioxide (ClO2 or OClO) is a molecule with both the species of atoms electronegative, chlorine being more electronegative than oxygenIt has 33 electrons, it is nonpolar, and it has ionization potentials of 1055 eV (OClO+ fragment) and 1337 eV (ClO+ fragment) (Probst et al, 2002)
Field et al (2000) have measured the total scattering cross sections in the range 20-500 meV, improving upon the earlier measurements of Gulley et al (1998) subsequently found to have had impurities The measurements of the latter authors up to 10 eV are much lower than the corrected values and they have been tabulated by Karwasz et al (2003) To remove the discontinuity at 05 eV, the values of Gulley et al (1998) have been adjusted by multiplying with a factor of 25, as shown in Table 301 and Figure 301
