| Abstract: | A direct method for characterizing organic material in atmospheric aerosols has been devised. Size segregated particulates, collected on ZnSe disks, were analyzed using Fourier Transform Infrared (FTIR) spectroscopy. The FTIR spectra were used to identify compound classes present in the aerosols; the distribution of functional groups varied with particle size and depended on whether the aerosol was collected at a primary or secondary receptor site. |
