✦ Synopsis

Siebert also gives a formula for the determination of the bond order b from the single-bond value f l : b = rbfhiri ri Moreover, we can tibe an even simpler relationship b = fb/fl up to b = 1.5 whenever the distances rl and Tb are not known. However, for bond orders over 1.5, we must use the formula b -0.29 7 0,71 fbbifl containing empirical correction factors; fb always is the experimental force constant. Finally, it should be mentioned, that also attempts where made to find relations between quantum mechanical data, as the electron density, and force constants [851. For small mole-cules (H20, NH3) force constants have been calculated from energy values obtained from an approximative wave function [86J.
