Dibromomethane (CH₂Br₂) is a strongly polar molecule that has 78 electrons. Its electronic polarizability is 10.37 × 10⁻⁴⁰ F m², dipole moment 1.42 D, and ionization potential 10.50 eV. The molecule has nine vibrational modes as shown in Table 56.1 (Shimanouchi, 1972).

56.1 IONIZATION CROSS SECTIONS

Bart et al. (2001) have measured the ionization cross sections as shown in Table 56.2 and Figure 56.1.

56.2 ATTACHMENT CROSS SECTIONS

Attachment cross sections unfolded from Swarm experiments by Sunagawa and Shimamori (1997) are shown in Table 56.3 and Figure 56.2.
