متن کاملEffects of halogens on European air-quality.
Halogens (Cl, Br) have a profound influence on stratospheric ozone (O3). They (Cl, Br and I) have recently also been shown to impact the troposphere, notably by reducing the mixing ratios of O3 and OH. Their potential for impacting regional air-quality is less well understood. We explore the impact of halogens on regional pollutants (focussing on O3) with the European grid of the GEOS-Chem mode...
متن کاملEffect of Pressure on Intermolecular Bonds in Solid Halogens
A bond charge model has been developed for the description of the pressure dependence for the Raman-active zone centre phonon frequencies of CI, Br and I. The increase in covalency of the intermolecular bonds shows up in increasing values of the bond charges under pressure. The halogens CI, Br and I form isomorphic molecular crystals. The structure is orthcrhombic with two molecules per primiti...
متن کاملCarcinogenicity studies on halogenated hydrocarbons.
A series of halogenated compounds was tested by oral intubation in 200 Osborne-Mendel rats and 200 B6C3F1 mice of both sexes. Carbon tetrachloride, used as a positive control, induced liver and adrenal tumors in mice and neoplastic nodules in the livers of rats. 1,2-Dibromoethane and 1,2-dibromo-3-chloropropane caused stomach tumors with many metastases in both rats and mice. Chloroform, known ...
متن کاملComputational Survey on the Effect of Changes in Halogenated Compounds on the structural properties in Chlorpromazine
In this study, on the combination of chlorpromazine with two aromatic rings, halogens are attached to the rings, and changes in the angles and lengths of the ipsos are calculated. Calculations show that by changing the halogen based on the amount of electronegativity, the magnitude and variation of the angular lengths The lengths of the links also change in the following order. The angles of th...
