Summary
-
1.
The bond energy U0 and frequency ω may be calculated for diatomic molecules via a simple classification in which the principal features are constancy in Ae2 and identical relation of (−U0) to D0. The average deviation of the calculated ω from the observed value is 5%, with deviations of 10–15% for 12 molecules. The calculated U0 agree with experiment largely within the limits of experimental error.

2.
The unknown vibrational frequencies are deduced for certain molecules, and estimates are given for the dissociation energies of BI, BaI, and CTe, as well as estimates for the electron affinities of As, Ge, and Sn.
