... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...
