A Portable Monitor of Atmospheric Pollutantsper cent. The need for such monitors arises from public concerns about the quality of ambient air, particularly the deleterious effects of chemicals advertently or inadvertently released into the atmosphere. Potential users of such monitors are industry, environmental authorities, waste disposal companies, and even private individuals.

Metal Ion-Nucleic Acid Interactions as Studied by Fourier Transform Infrared Spectroscopy’ ./. (A-DNA), C2’./. (B-DNA) and C3’./. (Z-DNA). These bands have been observed in FT-IR spectra of metal ion-nucleotide adducts, as well as, in metal ion-DNA adducts, in the regions, 600–900 cm. and 1000–1700 cm., similar to Raman spectra.
