Gaseous Carbonic Acid Trapped And Analyzed
Carbonic acid, an elusive but important compound in geochemical, physiological, and atmospheric processes, has been trapped and analyzed spectroscopically in the gas phase by a team of researchers headed by chemists in Austria (Angew. Chem. Int. Ed., DOI: 10.1002/anie.201004729). H2CO3 plays key roles in regulating blood pH, acidifying oceans, and dissolving minerals. The compound has been studied previously as a solid, but the gaseous species had escaped direct detection because it rapidly decomposes . . .
