Abstract

Abstract : The magic number boron cluster B13 + previously termed as a "molecular Wankel motor", is predicted to exhibit an exceptional fluxionality already at low temperatures. In their Communication onpage 505 ff., K. R. Asmis et al. spectroscopically confirm the structural assignment to a planar boron double wheel species and present the first experimental evidence for the quasi‐rotation of the inner B3 ‐ring using cryogenic ion vibrational spectroscopy of B13 + combined with density functional theory computations and Born–Oppenheimer molecular dynamics simulations.
