The detection and quantitation of y-emission from is accompHshed by well counting. A thaUium-activated sodium iodide crystal, having a well... [Pg.439]

Pimentel and his coworkers3,32 and later Pollack33 have observed stimulated emission from I(5aPyt) in the flash photolysis of a number of iodides, described by the processes... [Pg.14]

The weak emission from 52Pr ) observed when bromine and chlorine atoms are allowed to react with hydrogen iodide has been studied by Polanyi et al.38 Although the relative contributions from the reactions ... [Pg.35]

An examination of the emissions from Mt. Etna, Vulcano, Kuju, and Satsuma-Iwojima has revealed the presence of ethyl iodide (217). [Pg.20]

Quenching of the monomer fluorescence by iodide was used to distinguish the excimers formed at the phosphate surfaces from those in the bulk aqueous phase. Monomer emission from PBAC in the aqueous phase is quenched efficiently by iodide, whereas the negatively charged BAZrP galleries protect the bound PBAC and quenching is inhibited (Fig. 18). [Pg.527]

A somewhat different situation is presented by the pressure effects seen in the emission spectra of the rhenium(I) complex ReBr(CO)3(phen) and the copper(I) cluster Cu4I4py4 (where py = pyridine) and related species. The former displays strong MLCT emission in ambient temperature fluid benzene [35] solutions while the latter displays a strong emission from an cluster centered (CC) excited state assigned as having mixed d-to-s metal-centered and iodide-to-copper charge-transfer character [36]. In each case, the emission is markedly dependent on the rigidity of the medium, and... [Pg.72]

The effect of heavy atoms on the relative yields of fluorescence and phosphorescence has been investigated both by inserting Br and I substituents in the ring of deuterioporphyrin IX and its Zn derivative,340 and by adding ethyl iodide to the solution of a number of free base porphyrins.341 Other authors discuss the luminescence of protoporphyrin IX dimethylester after pulse radiolysis in benzene,848 and from monomeric and dimeric ethylenediamine-substituted protoporphyrin IX and some metal derivatives.343 Several reports consider the emission from porphyrins in Shpolskii matrices and other crystalline organic hosts.344-340... [Pg.197]

The process giving rise to enhanced methylation, and hence emissions, from rice-planted and flooded soil was postulated by Muramatsu and Yoshida (1995). This process entails the desorption of iodine from the solid phase of the soil due to low and consequent predominance of G in the soil solution. in the rhizosphere then becomes biomethylated by the effect of enzymes produced by soil microorganisms or roots (e.g., methyl halide transferase (Wuosmaa and Hager, 1990)). The methyl iodide produced... [Pg.115]

Reversible Electrodeposition of a silver iodide complex from a solution of 0.3 M Agl and KI or Rbl, and Ij in DMSO or diethyl malonate is an example for the third class of wet non-emissive electro-optic displays . As long as the silver content of the solution is high enough the solvent did not deteriorate when pulses of 50 V were passed through. The addition of AljOj, for preventing TiOj from agglomeration, and the use of RbAg4lj in DMSO as the solid ion-conductor established a cell which survive more than 10 cycles when operated at <2V drive, the realized response times were < 10 ms. [Pg.98]

In the NAA technique approximately 2 grams of PE powder are irradiated with neutrons obtained with a 500 keV neutron activator according to the following reaction H(D,n) He. Silicon is activated by the reaction Si(N,p) A1, and the concentration of silicon is then measured by counting the 1.78 MeV gamma ray emission from the decay of A1. A Conostan 5000 ppm Si standard is used for instrument calibration. Two 7.5 cm sodium iodide detectors are used to measure the 1.78 MeV gamma rays. [Pg.396]
