Papers
An ion trap time-of-flight mass spectrometer with high mass resolution for cold trapped ion experiments
TL;DR: This work designed and characterized a new experimental apparatus for probing chemical reaction dynamics between molecular cations and neutral radicals at temperatures below 1 K, and measures the performance of this system.

Isomer-selected ion-molecule reactions of acetylene cations with propyne and allene.
Philipp C. Schmid,Philipp C. Schmid,James Greenberg,Than Lam Nguyen,James Thorpe,Katherine J. Catani,Olivia Krohn,Mikhail Miller,John F. Stanton,Heather Lewandowski +9 more
TL;DR: Long-range charge exchange with no complex formation is favored for allene, whereas charge exchange leads to an intermediate reaction complex for propyne and thus, different products, and this reaction displays a pronounced isomer-selective bi-molecular reactive process.

Quantum-state-specific reaction rate measurements for the photo-induced reaction Ca+ + O2 → CaO+ + O
Philipp C. Schmid,Mikhail Miller,James Greenberg,Thanh Lam Nguyen,John F. Stanton,Heather Lewandowski +5 more
TL;DR: In this paper, the authors show that controlling which internal states are populated can be used to manipulate the reactivity of atoms and molecules, and can be done at different rates depending on their internal quantum states.

Isotope-specific reactions of acetonitrile (CH3CN) with trapped, translationally cold CCl+
Olivia Krohn,Katherine J. Catani,James Greenberg,Srivathsan P. Sundar,Gabriel da Silva,Heather Lewandowski +5 more
TL;DR: This work represents one of the first studied reactions of a halogenated carbocation with a nitrile and the first exploration of CCl+ with aNitrile, and stimulates questions regarding the strength and role of the nitriles functional group.

Reactions of translationally cold trapped CCl+ with acetylene (C2H2)
TL;DR: Ion-neutral chemical reactions are important in several areas of chemistry, including in some regions of the interstellar medium, planetary atmospheres, and comets, and in extraterrestrial environments.
