Predicted more than 40 years ago, the first direct evidence of N5‐hydrogen blocking is provided by the investigation of a peroxy‐flavinium intermediate. In their Research Article on page 15412 ff., J. Roithová and co‐workers show that mass spectrometry and ion spectroscopy can be used to trap and characterise intermediates with a life span below 1 s and thus fill in missing pieces in photochemical catalytic cycles.
