Consider three molecules, H79Br and deuterated molecule D79B and H$1 Br. The lowest energy transition for H79Br is 8.48572 cm-1. Compute the bond length of H79Br. Next compute the change in bond length by deuteration. Finally, briefly comment on how isotopic exchange changes both vibrational and rotational spectra. How are these changes similar, how do they differ? Is the exchange of H or Br more important for each case?
