Cadmium, Copper, Mercury, and Zinc Ions as Inorganic Probes in Phosphorimetric Analysis of Nucleosides.

Abstract

Figure 2. Excitation profile of adrenochrome. (a) Absorption spectrum. (b) 1679 cm -1, (c) 1628 cm-1, (d) 1474 cm-1 gen substituent at C-6. In noradrenochrome, there is a weak band at 1585 cm-1 visible as a shoulder on the water band. It is quite possible that C=C bands of the other aminochromes are obscured by water scattering, on which these bands are superimposed.

External heavy atom effect on detection limits and lifetimes of phosphorescence in time resolved laser excited phosphorimetry

“…Boutilier et al (48) studied the effect of silver and iodide ions on the phosphorescence of nucleosides and found silver ion to improve detection limits 20-to 50-fold. Other metal ions (Cd(II), Hg(II), Zn(II), and Cu(II)) have been studied as heavy atom perturbers (49,50) at 77 K and Ag(I) and T1(I) at room temperature on filter paper (51)(52)(53).
