Notes:
An internally consistent “valence-optical” scheme of additive bond and group polarizabilities, obtained from analysis of electric birefringence, refractivity and Raman intensity data, is shown to apply to a series of compounds of Group IVB elements. For all M-halogen bonds considered (M = Si, Ge or Sn; halogen = C1, Br or I), only the positive option for ±γ, the bond anisotropy from Raman intensities, is compatible with the scheme. The negative alternatives for γ lead to results which are anomalous and in some instances not physically meaningful. This procedure permits a definitive resolution of the problem of the sign ambiguity in ±γM-halogen.
