Abstrakt: The “bond order—bond length”, “bond length—average percentage s-character”, and “bond order—bond p-shortening” relationships have been obtained for CN and CO bonds. It has been shown that the differences in bond lengths are due chiefly to the specific features of the s-bonds. The observed relationship between the length of the s-bond and the average percentage s-character is linear. It has been noted that the bond lengths are most sensitive to the p-order when it changes in the range 0.3–1.0. For CC, CN, and CO bonds, relationships have been obtained between the p-order and the force constants, and for the single bonds the relationship between the average percentage s-character and the force constants has been obtained.
