Stability and Dissociation Dynamics of the Low-Lying Excited States of Ozone
نویسندگان
چکیده
This paper reports an investigation of the stability and dissociation dynamics of the low-lying singlet and triplet states of ozone (O3) using coincident photoelectron and photofragment translational spectroscopy. These experiments provide an upper limit of 0.5 μs for the lifetime of the low-lying excited states of O3. The A2 and B2 states dissociate with nearly all available energy appearing in translation. Dissociation of the higherlying B1 and A2 states produces rotationally and possibly vibrationally excited O2 products. The product translational energy distributions indicate that the B1 state dissociates nonadiabatically to ground-state O(3P) + O2(Σg) products.

Energy Balance and Gas Thermalization in a High Power Microwave Discharge in Mixtures
The dynamics of fast gas heating in a high power microwave discharge in air, is investigated in the framework of FDTD simulations of the Maxwell equations coupled with the fluid simulations of the plasma. It is shown that, an ultra-fast gas heating of the order of several 100 Kelvins occurs in less than 100 ns. The main role in the heating is played by the electron impact dissociation of , diss...

متن کاملNon-adiabatic effects within a single thermally averaged potential energy surface: thermal expansion and reaction rates of small molecules.
At non-zero temperature and when a system has low-lying excited electronic states, the ground-state Born-Oppenheimer approximation breaks down and the low-lying electronic states are involved in any chemical process. In this work, we use a temperature-dependent effective potential for the nuclei which can accommodate the influence of an arbitrary number of electronic states in a simple way, whi...
