Energy bond translational

However, if there is no other exothermic pathway available, all the intermediate can do is revert to reactants. In such a situation, the more favorable the addition process is, the more internal energy is in the intermediate and the faster the reverse dissociation will occur. The better the addition is thermochemically, the worse it is kinetically. For the proton transfer pathway (6b), the neutral methanol product can carry off the excess energy as translational energy (and capture some of it in the newly formed OH bond) and the reaction proceeds. 

On the other hand, the dynamics of the bond dissociations (i.e. the motion of the representative wave packet on the potential energy surfaces of ground and excited states for the various molecular entities) turns out to be always the same. This is concluded from the fact that the final state of the desorbing NO stays constant all energy distributions, translational, rotational, and vibrational, as well as their correlations, are identical despite the strong variations of cross sections [14, 96], These characteristics are compatible with the proposed TNI mechanism (see item 2 in... 

Another interesting system is C1H- -Ar. Although it has not been studied experimentally, a close coupling calculation has shown that this cluster dissociates with a rate of 4 X 10 sec (Hutson, 1984). The HCl bond absorbs infrared radiation at 2886 cm f Since the binding energy is 116 cm, we have a total of 2770 cm" of energy to dispose. Suppose first that the decay converts all of this energy into translations. If... 

Formation of steps and kinks always requires energy the translational symmetry of the surface is lifted, bonds are broken, and danghng bonds may occur. If the process would be ewithermic, that is, the formation energy would be negative, such a surface would be instable against roughening because of the spontaneous... 

When a substance is heated, the kinetic energy of atoms and molecules increases. E.g., if methane is heated, the kinetic energy of translation, vibration and rotation of methane molecules increases, as discussed in section 1.2. As heat is applied, higher vibrational states are increasingly populated. In higher vibrational quantum states, the average C-H bond distance increases until finally the C-H bond breaks. The result is the formation of a methyl radical and a hydrogen atom.
