The effects of D irradiation have been analyzed by infrared spectroscopy. The results indicate that HD forms by abstraction of hydrogen atoms chemisorbed in the hydroxyl groups of silicate grains. The formation process occurs for grain and atom temperatures relevant to photodissociation regions.STAMPAenConference paper10.1017/S17439213190088342-s2.0-85094854509https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/issue/7AA4A73FABCBFF4BD0D9E2CFD327926Chttps://api.elsevier.com/content/abstract/scopus_id/85094854509FIS/05 - ASTRONOMIA E ASTROFISICA
