A new paradigm is emerging in the field of photochemistry modelling in planetary atmospheres. The emphasis is placed on the accurate predictions of the models and the quantification of their uncertainties. In order to improve photochemical models predictions (see Fig 1.), it is necessary to identify in chemical schemes the key reactions that should be measured in priority at conditions relevant to planetary atmospheres. We discuss the notion of key reactions in chemical scheme and we compare several methods dedicated to the search for key reactions. This work focuses on the methods that have been published in the field of hydrocarbons photochemistry for giant planets and Titan [111]. These methods can be grouped into three families: determination of production paths, local sensitivity analysis methods and global sensitivity analysis methods. We show that current hydrocarbons photochemical schemes are characterized by large uncertainty factors of their rate constants and that global methods should be preferred to infer key reactions.
