Biography
Prof. Muyskens grew up in New Jersey and received his bachelor’s degree in Chemistry from Central College in Pella, IA, and his Ph.D. degree in Physical Chemistry from the University of Wisconsin-Madison under the mentorship of F. Fleming Crim. His thesis work focused on energy transfer in IR-laser excited hydrogen fluoride and deuterium fluoride gas using a chemical laser to monitor the time-dependent exchange of energy. He began his teaching career at app (formerly "College") where his research interests have focused on the interaction of light and molecules. He has enjoyed sabbaticals that have taken him to New York City, Riverside, CA, and Lausanne, Switzerland. Prof. Muyskens enjoys working in the laboratory on research experiments, computer modeling calculations or improving the teaching of physical chemistry laboratory. He also enjoys reading, doing puzzles, photography, and being outdoors, doing activities such as hiking, running, and biking.

Research
We study the fluorescence and photoacidity of natural coumarin compounds. We use absorbance and fluorescence spectroscopy and computer modeling to deduce dynamic interactions with solvents and isomers. Recently in our lab we made a new coumarin that is highly fluorescent that we have named knightletin. Three of the four most recent publications are in this area.
In previous work, we used a laser-based photochemical technique to study the elimination of hydrogen fluoride (HF) from fluorine containing organic molecules in the gas phase. Our focus has been on two molecules, formyl fluoride and trifluoroacetylacetone, which give remarkably different results. The goal is to learn fundamental details about how ultraviolet laser-excited molecules fall apart. Our infrared laser probe technique gives us information about how much vibrational and rotational energy is released into the HF molecule produced in the reaction. A new, NSF-funded, tunable laser system greatly expands our ability to use ultraviolet laser pulses to initiate chemical reactions. Ultimately, our experimental data is used to test theoretical approaches to modeling these kinds of light-based reactions.
