In this repository, all underpinning data for the figures included in the manuscript "Experimental absolute cross sections for the reaction of isobutane (CH(CH3)3) with [CH2O]•+ isomers" is presented. 

Cross sections in the absolute scale are separated into experimentally measured values and the predictions of the Langevin capture model, with full details given in the main text of the manuscript. Experimental cross sections are then further separated into the datasets included in each of the figures (both in the main text and the supporting information). All data is presented as TXTs with the columns corresponding to the data labelled according to the m/z ratio, with all cross sections in the absolute scale given in square angstroms.
