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 کاملThe ultraviolet absorption spectra of the pyrimidine ribonucleosides and ribonucleotides.
It is well known that the high and characteristic absorption of nucleic acids in ultraviolet light is due to the absorption of their purine and pyrimidine components. Several workers have measured the absorption curves of the aminoand oxypurines (l-3) and Jordan has obtained similar data for adenosine and guanosine and for the corresponding nucleotides (3). In the latter instances substitution ...
متن کاملAlloxan and dialuric acid; their stabilities and ultraviolet absorption spectra.
It was the purpose of this investigation to determine the ultraviolet absorption spectra of alloxan and dialuric acid. Previous investigators (l-3) reported that these substances had absorption spectra without definite maxima. However, since preliminary studies indicated that maxima were present under certain conditions, it was thought that a more careful investigation should be made. Although ...
