It's a kinda magic! Contrary to conventional wisdom that OH bonds associated with dangling hydrogen atoms and those in the H 3 O + ion in molecular clusters display characteristic peaks in IR spectra, a dynamic effect makes such peaks disappear, even in the gas phase at low temperatures. This finding helps solve the long‐standing problems of magic and antimagic protonated water clusters with 21 (top structures) and 22 (bottom structures) water molecules.
