Complex Constants and Ultraviolet Absorption Spectra
The complex formation between Cu (I) Cl and Cl was investigated in a 1 M HC104 ionic medium at 22 °C. In saturated CuCl(s) — Cl'-solutions over the concentration range 0 — 0.25 M Cl" the only complexes observed are CuCl2" and CuCl32-. The complex constants for the formation of these complexes are l o g ß n = —1.31 and log / ? 1 2 = —1.6 respectively. The UV-absorption spectra of CuCl2~ and CuCl...
متن کاملThe ultraviolet absorption spectra of proteins.
The absorption spectra of proteins have been made the subject of considerable study. For the greatest number of proteins there has been demonstrated a broad band with a peak at about 280 rnp and a minimum, on the short wave-length side, at about 250 m,u (1). From quantitative studies of simple proteins, this band could be correlated with the presence of tyrosine, tryptophan, and phenylalanine (...
متن کاملUltraviolet-absorption Spectra of Dry Bacterial Spores.
Bailey, Glen F. (Western Regional Research Laboratory, Albany, Calif.), Saima Karp, and L. E. Sacks. Ultraviolet-absorption spectra of dry bacterial spores. J. Bacteriol. 89:984-987. 1965.-The possibility of obtaining reasonably satisfactory ultraviolet-absorption spectra of dry spores embedded in KBr has been demonstrated. Such spectra show the three peaks characteristic of calcium dipicolinat...
متن کاملModeling Mid-Ultraviolet Spectra. I. Temperatures of Metal-Poor Stars
Determining the properties of remote globular clusters and elliptical galaxies using evolutionary population synthesis requires a library of reliable model stellar fluxes. Empirical libraries are limited to spectra of stars in the solar neighborhood, with nearly solar abundances and abundance ratios. We report here a first step towards providing a flux library that includes nonsolar abundances,...
متن کاملThe absorption spectra of benzene derivatives in the vacuum ultraviolet.
New photographs of the far ultra-violet spectrum of benzene are presented. The absorption from 2000 to 1800A (Amlx, c. 1980A) is regarded not as a part of the much stronger absorp tion of peak at 1790 A but as due to a separate transition. Sharp bands lying at 1790 A represent the first member of a previously reported Rydberg series. The spectra of toluene, xylene, monochloroando-dichlorobenze...
