Abstract
Scarcity of data for free diatomic molecules suggests interpolation Interpolated data acquires credibility if existing data exhibit systematic trends. Such trends suggested the proposed periodic table. In the $Z_{1}Z_{2}$ (molecule $Z_{1}Z_{2}$) plane, periodicity of physical data (e.g. $D_{o}, r_{e}, $k) is seen primarily in the $Z_{1}$ = constant, $Z_{2}$ = constant directions and secondarily In the homonuclear direction. The periodic table consists of partitioned sections of the $Z_{1}Z_{2}$ plane stacked vertically into blocks. With few exceptions ground state designations are invariant in the isoelectronic direction and for vertical (isovalent) sequences of molecules. Ions can be arranged in blocks translated progressively in the homonuclear direction $r_{e}$ has been predicted for approximately 250 molecules by curve-fitting certain isovalent sequences with the function $r_{e}=A+\ln\sqrt{x;}$ e.g. for BeF, MgF, $\ldots$, RaF, $x = 1, 2, \ldots, 6$ and $A = 1.38$. Predictions extend to super-heavy quasimolecules and molecules with superheavy atoms.
