Abstract

There are two different adsorption States of CO on amorphous solid water (ASW): one adsorption state consists of CO interacting with non-hydrogen-bonded (dangling) OH, while the other consists of CO interacting with bonded OH. Photoirradiation onto ASW at 157 nm induces CO₂ formation through the reaction of CO with OH, where OH originates from the photodissociation of H₂O ice. The preferential formation of CO₂ would explain the missing infrared CO band in the observation of interstellar ice particles.
