Summary on Grant Application Form |
|
The photodissociation of atmospherically important molecules will be studied using state-of-the art theoretical methods. The absorption spectra and photodissociation dynamics of 02, N20 and 03 will be the main focus of the research. The absorption spectrum and photodissociation of 02 will be computed throughout its whole spectral range. Particular attention will be paid to the relative probability for the production of the different spin-orbit fine structure states of the oxygen atom (i.e. 3P2, 3P1, 3PO, 1 D2, 1 SO), as well as to vector correlation and alignment effects. The calculations will be used to explain modern experimental results. For N20 + by --> N20) + 0(1 D2) the product rotational quantum state distribution of N2 will be computed as well as the alignment of the MJ sub-states of 0(1 D2). The explanation of the strong alignment, which has been experimentally observed, will involve consideration of the role of spin-orbit coupling and of electronically non-adiabatic transitions in the dissociation dynamics. For 03 the emphasis will be directed towards explaining the recently observed large cross sections for producing spin-forbidden photolysis products. The triplet potential energy surfaces and the spin-orbit coupling matrix elements between singlet and triplet states will be computed and used to explain these findings.
