There are few methods suitable for on-line chemical analysis of aerosol particles. Raman spectroscopy offers the possibility of identifying the chemical species in aerosol particles because the spectrum is specific to the molecular. structure of the material, especially to the vibrational and rotational modes of the molecules. Raman spectra have been obtained for individual micron-sized particles placed on surfaces, levitated optically or by an eiectrodynamic balance, or by monodisperse aerosols suspended in a flowing gas. A few measurements have also been made for chemically mixed and poly disperse aerosols. The Raman spectrum of a spherical particle differs from that of the bulk material because of morphology-dependent resonances that re.su It when the Raman scattered photons undergo Mie scattering in the particle. Methods have been developed for calculating the modified spectra (McNulty el al., 1980). 

Wallndfer et al. [963] investigated various anellated and alkylated polythiophenes [(polyisothianaphthene (PITN), polyison-aphthothiophene (PINT), poly(3-octylthiophene) (POT)] prepared by electropolymerization with resonance Raman spectroscopy at various laser wavelengths. " The spectrum of POT is dominated by a strong luminescence (which is related to some of the possible appUcations of this material). The main peak is around 1460 cm ...
