1) Chemical bond property 
The average distance between the nuclei of two bonded atoms in a stable molecule.
In molecular geometry, bond length or bond distance is the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule. == Explanation == Bond length is related to bond order, when more electrons participate in bond forma...
(from the article `spectroscopy`) As a molecule undergoes vibrational motion, the bond length will oscillate about an average internuclear separation. If the oscillation is harmonic, ... ...Figure 10. The energy minimum of this curve corresponds to the observed bond length of the molecule. The depth of the minimum is (apart from a ... ...
