摘要：

The large, temperature-dependent scalar coupling constants between the metal-bonded hydrogen atoms in trihydrido complexes are caused by a mutual quantum exchange between the two identical forms, that is, by a coherent tunneling process. In this report the experimental findings are explained by the reaction pathway sketched below, in which a metastable dihydrogen complex is formed. [GRAPHICS]
