Spectra of pure HCl and HCl-SF6 mixtures were taken in the range 350 to 520 cm-1, and of HBr, HBr-SF6, HBr-CF4 in the range 310 to 470 cm-1. For the mixtures, clearly defined peaks are observed at frequencies in these regions for the ΔJ=2 selection rule of quadrupole-induced dipole absorption, direct dipole intensities being much weaker. Calculated molecular quadrupole moments from integrated intensities are QHCl=5.8×10-26 esu·cm2 and Q HBr=5.5×10-26 esu·cm2.
