Summary on Grant Application Form
The project will combine new advances in the fields of molecular quantum dynamics, ab initio electronic structure theory and optimal control theory to design laser pulses to bring about specific molecular transformations or reactions. The new aspects of the proposed research are the use of high level ab initio molecular electronic structure theory to compute the energy of the system in the presence of an electric field. This provides a far more accurate representation of the radiation-molecule interaction than has previously been attempted in the literature. Our recent work has confirmed our ability to make new, experimentally verifiable, theoretical predictions in the field of molecular photodissociation. The quantitative predictions arising from the present project will be the first in this field capable of experimental verification and will greatly advance the understanding of the mechanism of molecular excitations and transformations using femtosecond laser pulses. Besides constituting a major advance in the computation of molecule-field interactions the proposed work will take account of the rotation of the molecules in the presence of the radiation field, an essential aspect of the physics never before included in such modelling work. We will design laser pulses to excite specified vibration al-rotational states of the hydrogen molecule, to achieve isotope-selective photodissociation of first-row diatoms; to create chosen quantum states of atoms resulting from photodissociation processes, and to change HCN into HNC.
