Abstract

Time-resolved Raman spectroscopy of a levitated droplet is demonstrated as the droplet absorbs vapor from the surrounding atmosphere. As the concentration of the absorbed species inside the droplet increases, its contribution to the Raman spectrum increases. Acquisition time for each spectrum is about five seconds, allowing the study of reactions within individual aerosol droplets.
