Organophosphorus Proton Affinities from AFT-MS and Kinetic Method with Computational Values

After applying the atmospheric flow tube-mass spectrometry approach to ambient vapor detection of phosphonic acids and tributyl phosphate, we observed that few organophosphorus compounds have reported proton affinities in the literature. Phosphonate species that are structurally similar to chemical warfare agent simulants in particular are valuable to characterize, which is why a series of dialkyl alkylphosphonates were the primary subject of our most recent AFT-MS article accepted for publication by the Journal of the American Society for Mass Spectrometry entitled “Interrogating Proton Affinities of Organophosphonate Species Via Atmospheric Flow Tube Mass Spectrometry and Computational Methods.” This was a collaborative effort with Ben Bythell at the University of Missouri-St. Louis, who computed lowest-energy structures and corresponding proton affinities based upon theory for the eight organophosphorus species assessed with the kinetic method, as well.

Dr. Clowers Recognized for Early Career Achievement

In the Spring Semester of 2015, Dr. Clowers was recognized within the College of Arts and Sciences at Washington State University for Early Career Achievement.  The College of Arts and Sciences celebrated achievements in teaching, research, and mentoring at its third annual Appreciation and Recognition Social on April 22, 2015.  Dr. Clowers was one of the nineteen faculty and staff, and six graduate students from across the college who were honored for their contribution to the WSU community and their commitment to excellence.


Feynman Lectures Online

While many have heard of the legendary lecture series, few can claim to have actually read each one.  Thanks to the folks at CalTech the barrier has now been lowered significantly.  Click the mug for the TOC.
