Sub-picosecond laser kinetic results for electron solvation in methanol were analysed using a wide variety of proposed kinetic models. All models are some kind of linear combination of exponential functions. The statistical analysis of the fit of different number of exponential functions showed that a sum of at least four exponentials is needed to describe the entire set of data. This result raises some problems concerning the interpretation of their electron solvation data by Shi et al.  using the two-step kinetic model, which only includes the sum of two exponential terms. The fit of this two-step model to different number of kinetic curves reveals that it would fit to any two curves detected at any wavelengths, but not for three or more. It is also clear from our analysis that the best available data set is not sufficient to decide between physically distinct mechanisms.
