Molecular desorption is the process whereby molecules are returned to the gas phase from the surfaces of interstellar dust grains. This term is especially used to describe desorption of material from the surfaces and bulk of interstellar ices in cold molecular clouds. Possible desorption mechanisms include thermal evaporation, photodesorption, heavy particle sputtering, cosmic ray ejection, and ejection of the products from highly exoenergetic surface reactions.
