The knowledge of the water vibrational actions permits us also to obtain another state-to-state property, the fraction of the vibrational energy, f vib H2O = 49 %, deposited in the bending, <fv2> and stretching <fv1,3> modes, which have also been experimentally reported. We obtained <fv2> = 22% underestimating the experimental evidence, 41%. This same behaviour was found in previous works from our group, analysing diatomic and polyatomic reactive systems. Different causes of the water bending excitation theory/experiment discrepancy were analysed, from subtle properties of the potential energy surface, such as the bending force constant describing the water molecule, to the previously noted ZPE violation problem. If this latter problem is important considering the total energy, it will be much more important when considered state by state. As a consequence of the classical nature of the QCT calculations an artificial flux of energy from the bending mode, v2, to the stretching modes, v1, v3, is observed (Figure ) which explains the low bending vibrational excitation observed as compared to the experimental evidence. In summary, the agreement is reasonably good taking into account that we are using classical tools to describe a state-to-state purely quantum property.
