The photodissociation of SO2 between 200 and 197 nm

摘要: Abstract Pump-probe experiments on the C state of SO2 have been performed to assess details oxygen photodissociation process between 197 and 200 nm. The findings show that a prompt dissociation event occurs in less than 265, but more 100 fs. reorganization internal energy 15 or 28 ps depending upon excitation energy; change lifetime represents contributions from asymmetric vibrational states seen previous experiments. In addition, long-lived species (lifetime >150 ps) exists does not decay timeframe our experiment. These are discussed comparison studies, particularly context an avoided crossing this region potential surface SO2.
