Spectroscopy
The force constant is a measure of the stiffness of a bond in a molecule, often denoted by the symbol 'k'. It quantifies the relationship between the force exerted on a bond and the displacement from its equilibrium position, playing a crucial role in determining vibrational energy levels and modes. A higher force constant indicates a stronger bond that requires more energy to stretch or compress, influencing the vibrational frequencies observed in molecular spectroscopy.
