Force constant of a bond

http://hyperphysics.phy-astr.gsu.edu/hbase/molecule/vibrot.html WebThe force constant k is a property of that specific bond and depends on the electronic structure of the molecule. It is the second derivative of the potential energy with respect to the bond length, evaluated at the minimum energy bond length. k can be calculated if given the frequency / wavelength of the IR absorption and the reduced mass.
