Research interests

Structural and Energetic Properties of Molecular Complexes: The main interest of the Phillips group is to identify and characterize complexes (associations of two otherwise stable molecules) that are apt to undergo substantial changes in structure in reopens to a change in their chemical environment. One example of the phenomenon is a "gas-solid structure difference", i.e., when a complex has a different structure in its gaseous state than in a crystalline solid. We are particularly interested in complexes hat show extreme sensitivity to their environment, and undergo significant structural changes in solution, or even in solid neon, argon, and nitrogen. The main tools of the research are low-temperature infrared spectroscopy, which allows us to detect structural change in inert, bulk solid samples near absolute zero, and computer models, which enable us to understand the underlying  features of these systems.
