Molecular Constants and Chemical Theories V. Some Remarks on Physical Constants and Theories of Higher Valence States

摘要

In answer to a recent article of Dr. Wheland, criticizing the previous papers of this series, some points of theoretical and experimental evidence are discussed. The criticism of the above paper is rejected in full (with the exception of a minor point on the calculation of ionic percentage contributions from bond moments). This article goes slightly beyond the previous ones in a number of points. Attention may be drawn to two of them. The question why different values of molecular constants are produced by the process of sharing or by a change of valency is discussed in greater detail. Furthermore, while maintaining that individual constants cannot distinguish between different structures or theories, it is shown that they can do so in conjunction. Indeed in conjunction they offer definite experimental evidence which supports the classical concepts but is not compatible with the semipolar double bond and its translation into resonance structures.
