Mid-IR spectroscopy and structural features of protonated carbonic acid in the gas phase.
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(2)CO(3) with a nominal gas-phase basicity of 724 kJ mol(-1).
