    • Note that only the complete matrix of the force constants has any physical chemical implication. In principle, it makes no difference if the force constants are determined theoretically (via the second derivatives of the molecular energy) or experimentally (via measured vibrational data). Nevertheless, in the case of large and unsymmetrical molecules there is no way to determine the complete matrix of force constants experimentally, because there are many more individual force constants than vibrational energies. On the other hand, the calculation of the complete Hessian matrices, using quantum chemical methods is only limited by the computing time. See: Califano, S. Vibrational States; 1st ed.; John Wiley & Sons: London, NewYork, Sydney, Tokyo, 1976.
