Joint physics and astronomy colloquium with Heather Lewandowski of University of Colorado, Boulder

Please join Heather Lewandowski of University of Colorado, Boulder during her joint physics and astronomy colloquium entitled, “Watching Chemical Reactions Happen One Molecule at a Time” via zoom at 3:15PM.  Reactions between ions and radical molecules play an important role in the chemistry that drives dynamics in the interstellar medium and during combustion of hydrocarbons. Unfortunately, experimental measurements of these reactions are very challenging, and thus very rare. We use tools borrowed from the cold atom community to measure ion-molecule reactions in a well-controlled environment. Here, we can study reactions between atoms and molecules in single quantum states at low temperatures. Our high sensitivity allows us to study reactions where the reaction rate can be as low as one reaction per minute. I will present the capabilities of this cold ion-molecule reaction apparatus and some example reactions we have been able to study using this new system.
