Polarized laser photolysis coupled with resonantly enhanced multiphoton ionization and velocity map ion-imaging detection will be used to determine the electronic angular momentum polarization of the atomic photofragments of atmospherically important triatomic molecules. A skimmed, pulsed molecular beam of the molecule of interest seeded in an inert gas will be crossed by radiation from the polarized photolysis and probe lasers. The O(3P) products of molecular photodissociation will be ionized using two-photon resonant transitions around 225nm, and velocity mapped onto the plane of a twodimensional imaging detector. The experiments will involve measuring the dependence of the resulting ion-images on photolysis and probe laser relative polarization (linear or circular). We will probe the O-atom photofragments in systems in which they are partnered by (i) closed-shell molecular coproducts (ii) open shell coproducts with zero total orbital angular moment, but non-zero electron spin, and (iii) open shell coproducts with both non-zero spin and orbital angular momentum. The molecular photodissociation systems proposed for study under these categories are (i) N20, CO2, OCS, and CS2 (ii) 03, and S02, and (iii) N02, and CI02.
