Molecular forces in a triatomic molecule
1. Bond-angle potential is designed to reproduce the bond geometry in molecules, which is in turn controlled by hybridization of atomic (electronic) orbitals
2. The bending energy equation is also based on Hooke's law.
3. This equation estimates the energy associated with vibration about the equilibrium bond angle.
4. The larger the value of 'k', the less energy is required to deform an angle (or bond) from its equilibrium value.
5. The 'kΘ' parameter controls the stiffness of the angle spring.
