Journal ArticleDOI
The roaming atom: straying from the reaction path in formaldehyde decomposition
David Townsend,Sridhar A. Lahankar,Suk Kyoung Lee,Suk Kyoung Lee,Suk Kyoung Lee,Steven D. Chambreau,Arthur G. Suits,Arthur G. Suits,Arthur G. Suits,Xiubin Zhang,Jaime L. Rheinecker,Lawrence B. Harding,Joel M. Bowman +12 more
TL;DR: Quasi-classical trajectory calculations performed on a global potential energy surface for H2CO suggest that this second channel represents an intramolecular hydrogen abstraction mechanism: One hydrogen atom explores large regions of the potentialEnergy surface before bonding with the second H atom, bypassing the saddle point entirely.
Journal ArticleDOI
Ionic Liquids as Hypergolic Fuels
Stefan Schneider,Tommy Hawkins,Michael Rosander,Ghanshyam L. Vaghjiani,Steven D. Chambreau,Gregory W. Drake +5 more
TL;DR: In this paper, the authors report on hypergolicity investigations of other fuel-rich anions, especially the dicyanamide anion, and a new path for transitioning these materials into bipropellant applications seems clear.
Journal ArticleDOI
Megapixel ion imaging with standard video
TL;DR: Chang et al. as discussed by the authors presented an ion imaging approach employing a real-time ion counting method with standard video, which employs a center-of-mass calculation of each ion spot (more than 3x3 pixels spread) prior to integration.
Journal ArticleDOI
Fourier transform infrared studies in hypergolic ignition of ionic liquids.
Steven D. Chambreau,Stefan Schneider,Michael Rosander,Tom Hawkins,Christopher J. Gallegos,Matthew F. Pastewait,Ghanshyam L. Vaghjiani +6 more
TL;DR: From the FTIR observations, biuret reaction tests, and initial ab initio calculations, a mechanism is proposed for the formation of N 2O, CO 2, and HNCO from the dicyanamide reactions during preignition.
Journal ArticleDOI
The roaming atom pathway in formaldehyde decomposition.
Sridhar A. Lahankar,Steven D. Chambreau,David Townsend,Frank Suits,John D. Farnum,Xiubin Zhang,Joel M. Bowman,Arthur G. Suits +7 more
TL;DR: The correlations between the vibrationalStates of H(2) and rotational states of CO formed following excitation on the 2(1)4(3) transition allow us to determine the relative contribution to molecular products from the roaming atom channel versus the conventional molecular channel.
