Photochemical Dynamics of a Trimethyl-Phosphine Derivatized [FeFe]-Hydrogenase Model Compound

August 17, 2018
Author(s)
Edwin J. Heilweil, Rachel L. Meyer, Tara M. Biser, Anet D. Zhandosova, Christopher J. Stromberg
Coupling photosensitizers with [FeFe]-hydrogenase model compounds can potentially create light- driven catalysts for production of hydrogen gas from acidic protons. Though there have been many studies on the synthesis, kinetics, and reaction mechanisms of

Effectiveness of Laser Safety Eyewear under Real-World Conditions

March 18, 2018
Author(s)
Christopher J. Stromberg, Edwin J. Heilweil, Joshua A. Hadler
Ultrafast lasers have become increasingly important as research tools in chemistry, which means laser safety is becoming more important. Laser safety glasses represent the last line of defense to protect users from potentially life-altering eye injuries

Ultrafast Laser Eyewear Protection: Measurements and Precautions

September 25, 2017
Author(s)
Christopher J. Stromberg, Joshua A. Hadler, Brian Alberding, Edwin J. Heilweil
Ultrafast laser systems are becoming more widespread throughout the research and industrial communities yet eye protection for these high power, bright pulsed sources still require scrupulous characterization and testing before use. Femtosecond lasers

Time-Resolved Infrared Studies of a Trimethylphosphine Model Derivative of [FeFe]-Hydrogenase

October 1, 2013
Author(s)
Edwin J. Heilweil, Christopher J. Stromberg, Melissa Johnson, James Thuman, Roger G. Letterman, Webster E. Charles
Model compounds that structurally mimic the hydrogen-producing active site of [FeFe] hydrogenases have been explored. In order to explore potential ground-state electronic structure effects on reaction mechanisms compared to hexacarbonyl derivatives, the

Time-Resolved Vibrational Spectroscopy of [FeFe-Hydrogenase Model Compounds

May 21, 2012
Author(s)
Edwin J. Heilweil, Christopher J. Stromberg
Fe2(μ-S2C3H6)(CO)6 is a model compound found to mimic the active site structure of the [FeFe]-hydrogenases. To observe the time-dependent behavior of this molecule, ultrafast ultraviolet (UV) or visible excitation with infrared (IR) probe measurements of
