Molecular bromine (Br₂) with 70 electrons belongs to the class of halogens. It has electronic polarizability of 7.81 × 10⁻⁴⁰ F m² and ionization potential of 10.516 eV. The dissociation (Br–Br) energy is 2.01 eV and the electron affinity is 2.55 eV. The (Raman) vibrational levels are 39.3, 78.2, and 117.1 meV for Δv = 1, 2, 3, respectively (Stammerich, 1950). The total vibrational excitation cross section at 0.5 eV is ∼2.5 × 10 ...
