The main purpose of potential constants,i. e., force and compliance constants, is to provide a quantitative understanding of bonding relationships. Compliance constants have been shown to possess several mathematical advantages over conventional force constants.1-3Compliance constants, however, are parameters which decrease in magnitude as bond strength increases; consequently, their use as bond strength parameters is not particularly satisfying. The desirability of a measure of bond strength which increases in magnitude as the bond becomes stronger, and at the same time possesses all the advantages of compliance constants is self evident. For this reason, the relaxed force constant Tii=1/Ciiwas introduced by Jones some time ago.4In the present communication, this approach is generalized to include relaxed interaction force constants. A brief discussion of their meaning is also presented.
