Johnson group members also held demos for New Haven area students as part of Yale's Chemistry Pathways program and participated as judges in the 22nd Annual New Haven Science Fair for K-12 students in the New Haven area.

After a succesful run as co-chair at the MIC GRS, Olga is preparing to chair the upcoming Molecular Interactions and Dynamics Gordan Research Seminar this July at Stonehill College in Easton, MA.

First year graduate student Nan Yang joins the group.  Welcome Nan!


Joe and his wife Liz welcome their daughter Isabel to the world.  Congratulations Joe and Liz!

Congratulations to Chinh for being awarded the National Science Foundation Graduate Research Fellowship for his proposal titled Systematic Capture and Structural Characterization of Proposed Intermediates in Homogeneous Catalysis!


Olga gave a contributing talk at the 251st ACS National Spring Meeting on characterizing the solvation shell of hydronium and hydroxide water clusters.

Over the past couple of months, the Johnson group has made some pretty major strides in the lab!

Our next generation machine, dubbed "the mini-machine" has come on-line. Even at a fraction of the size of our other instruments, the mini-machine can get down to comparable pressures and has great mass spec resolution, proving that "bigger isn't always better"! The mini-machine has also been used to test new capabilities, including a new way to record both mass and vibrational spectra using a PicoScope which allows us to bypass our old LeCroy o-scopes and boxcars.

T2 has also had some big changes recently. A second retro-reflectron was added to the back of the machine in order to give T2 double resonance capabilities. Additionally, one of our old imagers has been reinstalled onto the end of T2 and is now used to image the ion beam after it passes through the length of the machine. It makes it readily apparent how much the enizel lenses and deflectors affect the beam's trajectory!

Not to be left out, Tinman has also gotten a new capability! A make-shift glove box has been added to the front end in order to better store and prepare air sensative samples. 

The group went on their annual ski retreat to Stratton last week. Despite some icy skiing on the first day, they all had a blast!

Congratulations to Fabian and Steph who were chosen to give talks at the Molecular & Ionic Clusters Gordon Research Conference and Seminar (respectively) in Ventura, CA in January 2016! Another big congratulations to Olga for being the co-chair at the MIC GRS!

Mark gave the Nieuwland Lectures at the University of Notre Dame (three of them!), and had a chance to catch up with group alum Erica Price.

Mark gives the Harry Gunning Lectures (three of 'em!) at The University of Alberta.  Special thanks to Yunjie Xu and Wolfgang Jaeger for hosting!

After much hard work, we finally were successful in our attempts to capture and spectroscopically characterize CO2 activation! Our first small molecule activation paper was just accepted in Ang. Chem. Int. Ed. 

The Johnson Lab took their annual sailing trip this week. We had beautiful weather and some great wind! As always, thanks to Gary for captaining another awesome trip!
