説明
<jats:title>The nature of short hydrogen bonds</jats:title> <jats:p> Hydrogen bonding (H-bonding) unquestionably plays an important role in chemical and biological systems and is responsible for some of their unusual properties. Strong, short H-bonds constitute a separate class that, owing to their elusive characterization, has remained a point of contention over the past several decades. Using femtosecond two-dimensional infrared spectroscopy in conjunction with quantum chemical calculations, Dereka <jats:italic>et al.</jats:italic> demonstrate a powerful way to investigate the nature of short H-bonding (see the Perspective by Bonn and Hunger). Their quantitative characterization of multiple coupled motions in the model system of bifluoride anion [F-H-F] <jats:sup>−</jats:sup> in aqueous solution reveals several distinctive features of a crossover from conventional to short, strong H-bonding. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6525" page="160" related-article-type="in-this-issue" vol="371" xlink:href="10.1126/science.abe1951">160</jats:related-article> see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6525" page="123" related-article-type="in-this-issue" vol="371" xlink:href="10.1126/science.abf3543">123</jats:related-article> </jats:p>
