Abstract:	The vibrational frequencies for (C6H5)2Se, (C6H5)2Te, (C6H5)2Se2, (C6H5)2Te2, (C6H5)2Hg, and (C6H5-Se)2Hg are completely assigned and are consistent with the vibrational assignments for (C6H5)2O, (C6H5)2S, and (C6H5)2S2 previously reported. Further, whereas (C6H5)2O and to a lesser extent (C6H5)2S show vibrational spectra consistent with non-equivalence of the two phenyl rings attached to the central atom, the spectra of the other molecules show little evidence for such non-equivalency of the two phenyl rings. The infrared spectra of (C6H5-X)2Hg, where X = S or Se, and the spectra of structurally related molecules indicate that the mercury atom has no significant effects on the vibrations of the phenyl ring other than slight displacements of some frequencies as a result of interactions of central skeletal vibrations with ring vibrations. The vibrational assignments for (C6H5)2Te confirms the linearity of the Gordy Rule plot of the t-vibration for Group VIA Elements.
