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 Calvin University (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 and scholarship
We are using a laser-based photochemical technique to study the elimination of hydrogen fluoride (HF) from fluorine containing organic molecules in the gas phase. Our focus recently 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. Ultimately, our experimental data is used to test theoretical approaches to modeling these kinds of light-based reactions.
Our laser-based photochemical technique allows us to study the elimination of hydrogen fluoride (HF) from fluorine containing organic molecules in the gas phase. We will continue our investigation of two molecules, formyl fluoride and trifluoroacetylacetone, which give remarkably different results. This summer represents a unique opportunity to use a new, NSF-funded, tunable laser system, which greatly expands our ability to use ultraviolet laser pulses to initiate chemical reactions. The summer work continues our ongoing research program investigating photoelimination. Students working with us on the experiment will gain experience in gas synthesis and gas handling, several types of lasers, data acquisition, analysis and modeling. As part of the training the Calvin student(s), along with other students in our research consortium, will be trained in use of the new laser system by Purdue University laser specialist Hartmut Hedderich. The student(s) will also have an opportunity to meet with the other research groups in the consortium, possibly including a trip to Purdue University.
