DEUTERIUM CHLORIDE

CONTENTS

15.1 Attachment Data

References

 

Deuterium chloride (DCl) has properties very similar to hydrogen chloride (HCl) as expected. The attachment rate constant is 1.2 × 10⁻¹⁶ m³/s (Christophorou et al., 1968). The attachment cross sections are very similar to those for HBr, the ion formed being Br⁻ due to dissociative attachment. Table 15.1 shows the electron attachment data for DCl and HCl. Table 15.2 and Figure 15.1 show the attachment cross sections for DCl. The step-like structure in the attachment cross section curve is attributed to the vibrational modes ν = 4 to 6 (Abouaf and Tillet-Billy, 1977). The energy for vibrational excitation of DCl molecule is 266 meV.
