On page 2140 (DOI: 10.1002/jcc.24438 ) Y. Kanematsu, Y. Takano, and M. Tachikawa discuss the H/D isotope effect on a hydrogen bond between Yz and His190 of Photosystem II (PSII) using multicomponent quantum mechanics. The hydrogen bond showed a decrease in the donor‐acceptor distance upon deuteration, i.e. the inverse Ubbelohde effect, along with a strong dependence on the anisotropy of the potential energy profile. Such isotopic behaviors reasonably agreed with those of FHF – , which is one of the strongest hydrogen bonding systems. According to the agreement, PSII was confirmed as a biomolecular system containing the short strong hydrogen bond.
