Mid-IR spectroscopy and structural features of protonated carbonic acid in the gas phase

(Graph Presented) An anti trihydroxycarbenium ion is revealed to be the gas-phase structure of protonated carbonic acid by IR multiple-photon dissociation spectroscopy (see picture for calculated structure and comparison of experimental and computed spectra). Deprotonation yields anti-H 2CO3 with a...

Description
Summary:(Graph Presented) An anti trihydroxycarbenium ion is revealed to be the gas-phase structure of protonated carbonic acid by IR multiple-photon dissociation spectroscopy (see picture for calculated structure and comparison of experimental and computed spectra). Deprotonation yields anti-H 2CO3 with a nominal gas-phase basicity of 724 kJ mol -1. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
