Considerable attention has been dedicated during the last years to chlorofluorocarbons (CFCs). Much attention has been dedicated to their impact on the atmospheric processes, in relation to both the role in the reduction of ozone and in the greenhouse effect. Their complexation with atmospheric water affects their reactivity and it seems to accelerate, for example, the decomposition rate of freons in the atmosphere.[1] These complexes provide us the opportunity to study the effect of intermolecular bonding which can be interesting in connection with photochemical reaction dynamics.[2] In fact there is evidence that water molecules may have decisive influence on gas-phase reactions [3, 4] and there are many unusual features associated with the kinetics and energetics of hydrated chemical systems.[5, 6] Water molecules can stabilize the intermediates of such reactions but these effects are often difficult to distinguish. Experimental evidence can be accounted for by invoking pre-reactive complexes of haloderivatives with water.[7, 8]Water is a key solvent and provides the fundamental environment to the course of life. Water is often noncovalently bound to organic molecules or biomolecules and its internal dynamics in the formed complexs contribute to determine the properties of these systems.[9] Water plays an important role in (bio) organic reactions (molecular recognition), radiation absorption,[10] and in atmospheric dynamic
