Titan ionospheric chemistry


A new physical chemistry approach is developed in order to provide information necessary to improve the understanding of processes involved in the ionosphere of Titan. The complexity of the chemical processes occuring in the ionosphere calls for an improved description . (i) The uncertainty associated to laboratory measurements, and their propagation in the model schemes and (ii) the simplification of the chemistry scheme, in order to describe the complex behavior, without losing the physical meaning of results will be handled by means of statistical methods. (iii) From the laboratory measurements point of view, the structure of reactants and product in orders to identify the pathways leading to important process such as cyclisation, functionalization, etc will be described accurately by means of a ultra high resolution mass spectrometer. Historical results of our studies on the effect of internal and kinetic energy on the initial step of the chemical scheme will also be discussed.
