Infrared spectra of phenanthrene particles generated by pulsed rapid expansion of CO2 solutions

Author affiliations

Abstract

A new apparatus for the pulsed rapid expansion of supercritical solutions (RESS) is presented. Phenanthrene particles with diameters of 240 nm were generated by expanding dilute solutions of phenanthrene in CO2. The number size distribution and the shape of the particles were analyzed off-line with scanning electron microscopy and on-line with a scanning mobility particle sizer and extinction measurements. From these investigations and from infrared spectra of the aerosol particles, refractive index data for phenanthrene were determined in the mid-infrared region of the spectrum.
