Kinetic energy release distributions fitting with phase space

In contrast to the results obtained for dehydrogenation reactions, kinetic energy release distributions for alkane elimination processes can usually be fit with phase space theory. Results for the loss of methane from reaction 9 of Co + with isobutane are shown in Figure 10b. In fitting the... 

The success of the phase space theory in fitting kinetic energy release distributions for exothermic reactions which involve no barrier for the reverse reaction have led to the use of this analysis as a tool for deriving invaluable thermochemical data from endothermic reactions. This is an important addition to the studies of endothermic reactions described above. As an example of these studies, consider the decarbonylation reaction 11 of Co+ with acetone which leads to the formation of the... 

It should be apparent that phase space fitting of kinetic energy release distributions yields important thermochemical information for exothermic reactions with no reverse activation barrier. As another example, Co+ ions decarbonylate acetone (reaction 10) yielding a dimethyl cobalt ion as... 

In accordance with the considerations outlined in the previous section, a statistical kinetic energy release distribution should be observed for this system. As shown in Figure 7, the experimental distribution for this process can be fit very closely using statistical phase space theory, which yields a bond dissociation energy Do°(Fe -C5H5) = 55 + 5 kcal/mol. A reaction coordinate diagram for...
