Quantum tunneling during interstellar surface-catalyzed formation of water: the reaction H + H2O2 → H2O + OH† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c6cp06457d Click here for additional data file.

The final step of the water formation network on interstellar grain surfaces starting from the H + O2 route is the reaction between H and H2O2. This reaction is known to have a high activation energy and therefore at low temperatures it can only proceed via tunneling. To date, however, no rate constants are available at temperatures below 200 K. In this work, we use instanton theory to compute ...
