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.
