Comparison with the F1s data obtained for the reaction between an adsorbed BMP-TFSI monolayer and Li in Figure reveals little difference in the reaction behavior, despite the different BMP-TFSI : Li ratio. At least for the reaction pathways leading to F-containing reaction intermediates / products, the direct interaction with the graphite substrate does not seem to cause major changes in the reaction behavior between Li and BMP-TFSI. This is important also from fundamental aspects, since for the monolayer situation the reaction starts from coadsorbed and therefore positively charged Li, while for the thick multilayer film Li arrives as a neutral atomic species. Hence, there is a difference in the initial state of Li in the two cases, which, however, seems to have little impact on the reaction behavior.
