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