Abstract : The overall objective of this research is to establish the physical principles for achieving control over molecular motion through the introduction of tailor-made optical fields. During the past year, this effort has involved both basic theoretical developments, as well as selected applications. Particular emphasis was given to establishing the robustness of laser field designs to various inevitable uncertainties and errors that may arise. In addition, an entirely new algorithm based on quantum mechanical tracking was introduced as a basis for a comprehensive treatment for both molecular control, as well as the inversion of controlled dynamics, to learn about the underlying Hamiltonians. The application of these various theoretical efforts was made to high quality ro-vibronic population inversion and the selective dissociation of HCN. Finally, a fundamental controllability algorithm was established, with the capability of assessing whether it is feasible to reach acceptable degrees of control in any particular molecule.
