Context. Carbonic acid (H2CO3) is a weak acid relevant to astrobiology which, to date, remains undetected in space. Experimental work has shown that the β-polymorph of H2CO3 forms under space relevant conditions through energetic (UV photon, electron, and cosmic ray) processing of CO2and H2O-rich ices. Although its α-polymorph ice has been recently reassigned to the monomethyl ester of carbonic acid, a different form of H2CO3 ice may exist and is synthesized without irradiation through surface…

Linear and Helical Carbonic Acid Clusters.
TLDR
The present combined density functional theory and coupled-cluster theory work examines both the ribbon and the new helical spiral motifs in terms of relative energies, sequential binding energies, and electronic spectra which could potentially aid in distinguishing between the two forms.
Stabilizing the Exotic Carbonic Acid by Bisulfate Ion
TLDR
Bisulfate ion could efficiently stabilize all the three conformers of H2 CO3 and reduce the energy differences of isomers with H2CO3 in three different conformations compared to the isolated H 2CO3 molecule, suggesting all the optimized isomers of the complex have good thermal stability and could exist at finite temperatures.

Vacuum ultraviolet photoabsorption spectroscopy of space-related ices: 1 keV electron irradiation of nitrogen- and oxygen-rich ices
Context. Molecular oxygen, nitrogen, and ozone have been detected on some satellites of Saturn and Jupiter, as well as on comets. They are also expected to be present in ice-grain mantles within
Alpha‐Carbonic Acid Revisited: Carbonic Acid Monomethyl Ester as a Solid and its Conformational Isomerism in the Gas Phase
TLDR
This analysis provides evidence for the existence of not only single CAME molecules but also CAME dimers and water complexes in the argon matrix, where conformational isomerism is triggered in experiments through UV irradiation.
Probing the interaction between solid benzene and water using vacuum ultraviolet and infrared spectroscopy.
TLDR
These first systematic studies of binary amorphous mixtures in the VUV, supported with complementary IR studies, provide a deeper insight into the influence of intermolecular interactions on intramolecular electronic states with significant implications for the understanding of photochemical processes in more realistic astrochemical environments.
