a Fitted DTCCSD190KHe (blue line) and experimental values (black dots) at 5 drift voltages, in decreasing order, at 190 K. b Interconversion rate constant calculation simulation fitted to the ATDs obtained at the lowest drift voltage for which reasonable signal was obtained at: 295, 275, 210, 190 K from top to bottom. Black dots represent experimental values, and solid blue lines of panel (b) represent the calculated fit to the ATD. The schematic of the α-synuclein structure is adapted from AlphaFold Protein Structure Database82.
