Spectroscopic Observation of Gas-Phase Carbonic Acid Isolated in Matrix

Carbonic acid molecules were trapped from the gas phase in a solid noble-gas matrix at <10 K and studied by IR spectroscopy. The 2H and and 13C isotopologues were also examined. Gas-phase carbonic acid is thought to exist as a 1:10:1 mixture of two monomeric conformers and the cyclic dimer (H2CO3...

Description
Summary:Carbonic acid molecules were trapped from the gas phase in a solid noble-gas matrix at <10 K and studied by IR spectroscopy. The 2H and and 13C isotopologues were also examined. Gas-phase carbonic acid is thought to exist as a 1:10:1 mixture of two monomeric conformers and the cyclic dimer (H2CO3)2. This data is vital in the search for gas-phase carbonic acid in astrophysical environments. Peer reviewed
