Covalent bond refractions and the periodic table. I. Bonds to hydrogen

Abstract

On the preliminary assumption of the additive and constitutive nature of the parachor, P, and of the Lorentz-Lorenz refraction, R_L, the empirical relationship, P = _aR_Lⁿ+b, where a, b, and n, are constants, has been applied to values of these properties for covalent bonds between the elements of Groups IVB-VIIB and hydrogen. The resulting equations reproduce the experimental input data to a high order of precision, and they have been employed for the calculation of the refraction of numerous bonds hitherto unreported.
