The various nitro polynuclear aromatic compounds, including 1-nitropyrene, 9-nitroanthracene, 2-nitronaphthalene, and 2-nitrofluorene have been investigated by use of the surface-enhanced Raman scattering (SERS) spectrometry technique. Silver-coated substrates consisting of latex spheres on glass and filter paper and prolate SiO/sub 2/ posts on quartz were used. The limit of detection of 1-nitropyrene was found to be 0.3 ng. The SERS signals were enhanced over conventional Raman signals by a factor of 5 x 10/sup 6/ to 9 x 10/sup 6/ for 1-nitropyrene adsorbed on various SERS-active substrates. The production and practicality of SERS-active substrates with glass, paper, and quartz supports are discussed. 30 references, 6 figures, 1 table.
