The reaction, at first glance, seems simple. Combustion engines, such as those in your car, form carbon monoxide (CO). Sunlight converts atmospheric water into a highly reactive hydroxyl radical (OH). And when CO and OH meet, one byproduct is carbon dioxide (CO2) ­– a main contributor to air pollution and climate change.

But it’s more complicated than that. Before CO2 is formed, a short-lived, intermediate molecule, called the hydrocarboxyl radical (HOCO), is formed. The existence of HOCO was first proposed over 40 years ago, but the unstable nature of the molecule made it difficult, nearly impossible, to observe. The Ye group of JILA, however, has been closing in on the impossible.

The deuterated version of HOCO, called DOCO, was observed by Bryce J. Bjork, Thinh Q. Bui, Jun Ye, and their collaborators in 2016. Deuteration, or substituting a heavier version of the hydrogen atom, called deuterium, reduced signal...
