Deuterium bromide (DBr) has properties very similar to hydrogen bromide (HBr) as expected. The attachment rate constant for the molecule is 3.1 × 10−17 m3/s (Christophorou et al., 1968). The attachment cross sections are very similar to that for HBr, the ion formed being Br− due to dissociative attachment. Table 14.1 shows the electron attachment data for DBr and HBr.
