These data were generated by irradiating a gas mixture of argon and pyridine at 266 nm laser light. The cations thus produced were measured using a time-of-flight spectrometer. This procedure yielded the data for Figures 1 , 2, and 5. The electrons produced in this process were also measured using a velocity map imaging spectrometer. This yielded a 2-D image and the data for that has X and Y coordinate of the position of hit of the electrons on the detector along with the counts. This yielded the data for Figure 4.
