Isomer-selected ion–molecule reactions of acetylene cations with propyne and allene

Autor: Olivia Krohn, Katherine J. Catani, John F. Stanton, James Thorpe, Than Lam Nguyen, Philipp C. Schmid, James Greenberg, Heather Lewandowski, Mikhail Miller

Publikováno v: Physical Chemistry Chemical Physics. 22:20303-20310

One of the fundamental goals of chemistry is to determine how molecular structure influences interactions and leads to different reaction products. Studies of isomer-selected and resolved chemical reactions can shed light directly on how form leads t

Velocity-tunable beam of continuously decelerated polar molecules for cold ion-molecule reaction studies

Autor: Jason A. Bossert, Noah Fitch, Yomay Shyur, David Macaluso, Heather Lewandowski, James Greenberg, Olivia Krohn

Publikováno v: The Review of scientific instruments. 92(10)

Producing high densities of molecules is a fundamental challenge for low-temperature, ion-molecule reaction studies. Traveling-wave Stark decelerators promise to deliver high density beams of cold, polar molecules but require non-trivial control of h

Photoisomerization dynamics of trans-trans, cis-trans, and cis-cis diphenylbutadiene from broadband transient absorption spectroscopy and calculations

Autor: Martin Quick, Olivia Krohn, S. A. Kovalenko, Svetlana M. Sudarkova, Celin Richter, Ilya N. Ioffe

Publikováno v: The Journal of chemical physics. 152(22)

The photoisomerization path and dynamics of trans-trans (ttD), cis-trans (ctD), and cis-cis (ccD) 1,4-diphenyl-1,3-butadiene (DPB) in solution are studied with broadband transient absorption (TA) spectroscopy and quantum chemical calculations. For tt

Using isotopologues to probe the potential energy surface of reactions of C2H2++C3H4

Autor: Mikhail Miller, John F. Stanton, Katherine J. Catani, Thanh Lam Nguyen, James Thorpe, Heather Lewandowski, James Greenberg, Philipp C. Schmid, Olivia Krohn

Publikováno v: The Journal of Chemical Physics. 154:124310

Investigations into bimolecular reaction kinetics probe the details of the underlying potential energy surface (PES), which can help to validate high-level quantum chemical calculations. We utilize a combined linear Paul ion trap with a time-of-fligh

Isotope-specific reactions of acetonitrile (CH3CN) with trapped, translationally cold CCl+

Autor: Katherine J. Catani, Olivia Krohn, Heather Lewandowski, Srivathsan P. Sundar, G. B. da Silva, James Greenberg

Publikováno v: The Journal of Chemical Physics. 154:074305

The gas-phase reaction of CCl+ with acetonitrile (CH3CN) is studied using a linear Paul ion trap coupled to a time-of-flight mass spectrometer. This work builds on a previous study of the reaction of CCl+ with acetylene [K. J. Catani et al., J. Chem.
