The combination of laser photodissociation, action spectroscopy, and mass spectrometry to identify and separate isomers

Publikováno v: Chemical Communications. 58:9451-9467

The separation and detection of isomers remains a challenge for many areas of mass spectrometry. This article highlights laser photodissociation and ion mobility strategies that have been recently deployed to meet this challenge with focus on small m

Mass Spectrometry Imaging of Lipids using MALDI Coupled with Plasma-Based Post-Ionisation on a Trapped Ion Mobility Mass Spectrometer

Autor: Jesse Michael, Shadrack Mutuku, Boris Ucur, Tassiani Sarretto, Alan Maccarone, Marcel Niehaus, Adam Trevitt, Shane Ellis

Here we report the development and optimization of a mass spectrometry imaging (MSI) platform that combines atmospheric-pressure matrix-assisted laser desorption/ionization platform with plasma post-ionization (AP-MALDI-PPI) and trapped ion mobility

Actinic Wavelength Action Spectroscopy of the IO− Reaction Intermediate

Autor: Benjamin McKinnon, Samuel Marlton, Boris Ucur, Evan Bieske, Berwyck Poad, Stephen Blanksby, Adam Trevitt

Iodinate anions are important in the chemistry of the atmosphere where they are implicated in ozone depletion and particle formation. The atmospheric chemistry of iodine is a complex overlay of neutral-neutral, ion-neutral and photochemical processes

Five vs Six Membered-Ring PAH Products from Reaction of o- Methylphenyl Radical and two C3H4 Isomers

Autor: Adam Trevitt, Gabriel da Silva, Stephen Blanksby, C. A. Taatjes, David Osborn, John Savee, Matthew Prendergast, Oisin Shiels

Using VUV synchrotron photoionization mass spectrometry, quantum chemistry and RRKM kinetic modeling, our paper identifies the products formed when a substituted aromatic free radical (ortho- methylphenyl) reacts with two C3H4 isomers found in flames

Electrostatically Tuning the Photodissociation of the Irgacure 2959 Photoinitiator in the Gas Phase by Cation Binding

Autor: Samuel Marlton, Benjamin I. McKinnon, Nicholas Hill, Michelle Coote, Adam Trevitt

Our paper reports a combined experimental and computational investigation of the electrostatic tuning of Irgacure 2959, a Norrish-type I photoinitiator, in the presence of bound cations (H+ , Li+ , Na+ , K+ , Zn2+ , Ca2+ and Mg2+). Laser photodissoci

Reactivity Trends in the Gas Phase Addition of Acetylene to N-protonated Aryl Radical Cations

Autor: Adam Trevitt, Gabriel da Silva, Stephen Blanksby, Berwyck L. J. Poad, Cameron C. Bright, P. D. Kelly, Oisin Shiels

A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N- conta
