Kinetic-to-internal-energy transfer

Here again there is evidence that vibrationally excited CH4 + can react with some kinetic to internal energy transfer and produce ions which...

The evidence in Figure 2 for a kinetic energy threshold for reaction of excited H2+ with He does not support the assumption of a kinetic energy transfer process for the excitation of reactant H2+ with v < 5 in reactive collisions with He. If such processes were probable, a drastic change in the maximum value of Q or k might be expected. The transfer of less than 0.5 e.v. of kinetic to internal energy would add quantum states with v = 3 and 4 to the inventory of available H2 + reactant and increase the maximum value of k by a factor of 2. 

In the case of dissociative adsorption on surfaces there is an additional channel into which energy can be transfered, namely the conversion of the kinetic and internal energy of the molecule into translational energy of the fragments on the surface with respect to each other. In fact, in the dissociation of light molecules such as 1I2 on metal surfaces the dissociative adsorption probability is... 

Apart from the PD methods, all the other proposed methods are based on the transfer of ion kinetic energy to internal energy at higher amplitudes of the RF potential the main RF field is responsible for ion acceleration and for the related increase of ion kinetic energy. 

As the pressure in a pipe falls, the kinetic energy of the fluid increases at the expense of the internal energy and the temperature tends to fall. The maintenance of isothermal conditions therefore depends on the transfer of an adequate amount of heat from the surroundings. For a small change in the system, the energy balance is given in Chapter 2 as ... 

The activation energy for the charge reduction reaction is due to two factors the bond stretching and distortions of the originally near linear complex, so as to achieve the internal proton transfer and the increase of energy due to the Coulombic repulsion between the two charged products, a repulsion that leads to a release of kinetic energy on their separation.
