(V) Consider three molecules, H7ºBr and deuterated molecule D79Br and H$1Br. The lowest energy transition for H79B is 8.48572 cm-1. Compute the bond length of H7ºBr. 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?
