ABSTRACT

Ionization cross sections for both isomers of C2H4Cl2 measured by Hudson et al. (2001) are shown in Table 99.3 and Figure 99.1.

TABLE 99.1 Selected Properties of C2H4Cl2 Name Formula αe (F m2) µ (D) εi (eV)

1,1-C2H4Cl2 1,1-C2H4Cl2 9.61 × 10−40 2.06 11.04 1,2-C2H4Cl2 1,2-C2H4Cl2 8.90 × 10−40 1.83 11.04

Note:αe = electronic polarizability; µ = dipole moment; εi = ionization energy.
