Chemical Physics

Chemical physicists at JILA use advanced laser techniques to probe the structure and dynamics of matter during chemical reactions, i.e., during the making and breaking of chemical bonds.

JILA’s chemical physics research includes studies of molecular energy flow and optical/electrical properties of crystals, mapping of electron dynamics in materials and individual molecules, fabrication of nanomaterials, cooling of molecules through Stark deceleration and laser manipulation, and identifying short-lived molecules within interstellar and atmospheric combustion. These research endeavors advance our understanding of chemical reactions and inform the development of new materials.

The many different molecules trying to fill the binding site of octamethyl calix[4]pyrrole (omC4P)
Molecular Lock and Key: Decoding the Secrets of Ion Binding

Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and cleanup to drug delivery. In a series of new studies led by JILA Fellow and University of Colorado Boulder chemistry professor Mathias Weber, researchers explored how a specific ion receptor called octamethyl calix[4]…

Cold Coulomb Crystals, Cosmic Clues: Unraveling the Mysteries of Space Chemistry

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties…

Looking at a Cellular Switch

Although one might think it would be simple, the genetics of bacteria can be rather complicated. A bacterium’s genes use a set of regulatory proteins and other molecules to monitor and change genetic expressions within the organism. One such mechanism is the riboswitch, a small piece of RNA that can turn a gene “on” or “off.” In order to “flip…
