Hooke’s Law

The Hooke’s Law is a mathematical formula that relates the vibrational frequency of a spring connected to two spheres to the stiffness of the spring and to the masses of the spheres.



Vibrations of a covalent bond is thought to be similar to those of the above system.  Thus, the Hooke’s Law can be applied to the vibrations of a covalent bond.  Given below is the Hooke’s Law as it applies to a covalent bond.



According to the Hooke’s Law,
1.  All else being equal, the stronger the bond, the faster the bonds vibrates.

eg:



2.  All else being equal, the lighter the atoms linked by the bond, the faster the bond vibrates.

eg:
