Research Abstract

Atmospheric solid particles and aqueous droplets with diameter less than 100 micrometer, are generally called aerosols. It is concerned the environmental and ecological impact by the atmospheric contaminants which are concentrated in aerosol particles in recent years. In this work, we constructed an apparatus for terahertz microspectroscopy system. The final goals of this study are that uptake of gaseous substances to liquid droplets and the observation of a droplet formation from the condensation nuclei by means of terahertz spectroscopy.
