Vector Correlations in the 355 nm Photodissociation of N2O3
MetadataShow full item record
The 355 nm photolysis of N2O3, a molecule with applications in atmospheric chemistry and potential practical reagent use, is created by the dehydration of HONO. N2O3 is investigated using a three color photodissociation and REMPI to determine bipolar moments. This experiment shows the DC-sliced imaging ability to sort out multiple NO photoproducts, and the presence of N2O3 in the molecular beam even though it may not show up directly in the gas bulb. There have been no previously published photodissociation studies of N2O3, as LIF is not position sensitive, and therefore is not specific enough to sort through NO photoproducts with enough detail. In the N2O3 photofragmentation it is found that the molecular transition dipole (μ) is parallel to the photofragment recoil velocity (v), which is new information in the field of photodissociation. The μ-j correlation is shown to be not strictly perpendicular, due to a nonplanar confirmation of the ground state N2O3. This adds to the conclusion that velocity sliced imaging can assist in discriminating species that have a difference in product velocity. Further research suggestions are made.
