Many biochemical processes are stereospecific. An example is the physiological response to a drug that depends on its enantiomeric form. Naproxen is a drug which shows this stereo-specific physiological response. To better understand the stereo specificity of chiral substances, we observed the S₁ leftarrow S₀ transitions of R- and S-naproxen in the gas phase using rotationally resolved electronic spectroscopy. The results will be discussed.
