Reactive Collisions at the Cold Temperatures of Interstellar Clouds: H2CO +OH example

AutorRoncero, Octavio
Fecha de publicación3-jul-2017
CitaciónQRS XIV (2017)
ResumenA complex chemistry takes place in cold molecular clouds in the interstellar medium. The gas phase reaction for the formation of many organic molecules present a barrier and for this reason their formation are typically modelled at surfaces of ices. However, recently it has been found a non-Arrhenius behavior at low temperatures, below 100 K, with a fast increase of the rate with decreasing temperature [1-3] for the reaction of methanol with OH, which is known to have a barrier of about 0.3 eV. The reaction of formaldehyde with OH also shows this behavior [4]. This behavior is simulated with Quassi-Classical trajectory calculations on a full-dimension potential energy surface recently developed [4].
