Transition State Theory

1. significant progress with the variational formulation of classical TST, in which the objects of interest are transition 2. the study of quantum analogues of these generalized transition states, which has led to a practical and reliable rate theory for atom-diatom reactions; 3. the development of a quantum TST that avoids the separability ap­ proximation of conventional TST; 4. the use of the TST line of no return idea as an aid in the calculation of reaction rates from individual initial states; 5. the invention of an interpolating theory to connect the TST rate ex­ pressions for direct and complex reactions; 6. the use of variational TST to calculate capture cross sections in ion­ molecule reactions; 7. the resolution of a few questions concerning transition state symmetry.
