Exploring High‐Pressure Polymorphism in Carbonic Acid through Direct Synthesis from Carbon Dioxide Clathrate Hydrate
Abstract Carbon dioxide (CO 2 ) is widespread in astrochemically relevant environments, often coexisting with water (H 2 O) ices and thus triggering a great interest regarding the possible formation of their adducts under various thermodynamic conditions. Amongst them, solid carbonic acid (H 2 CO 3...
