Decreasing the energy of the electron beam in transmission electron microscopy (TEM) improves the stability of inorganic molecules, however, organic molecules become surprisingly less stable under these conditions. On page 622, E. Bichoutskaia, U. Kaiser, A. N. Khlobystov, and co‐workers analyse the interactions of the e‐beam with C–H bonds and are able to highlight the low atomic weight of hydrogen as a key issue. Exchanging protium for deuterium resolves the issue and brings atomic‐resolution TEM imaging of individual organic molecules closer to reality.
