In this study, the combination of Phenergan C17H2ON2S, in which two aromatic rings are present, are attached to the rings at carbon position 5 and 13 halogens, and the changes in the asymmetric parameter, the convex constants, and the chemical displacement of the lateral carbon atoms are calculated. It shows that with the change of halogen based on the electrone...

1-Carboxymethyl-3-methylimidazolium chloride {[cmmim]Cl} is utilized as a highly efficient and reusable catalyst for the synthesis of bis(indolyl)methanes by the condensation reaction of indole with arylaldehydes under solvent-free conditions at room temperature. In summary, the presented method have several advantages including simplicity, low cost, generality, efficiency, clean reaction profi...

Abstract. The atmospheric chemistry of halogenated species (Cl, Br, I) participates in the global chemical sink tropospheric ozone and perturbs oxidising capacity troposphere, notably by influencing lifetime methane. Global chemistry–climate models are commonly used to assess budget its sensitivity emissions precursors, as well project long-term evolution. Here, we report on implementation sour...

Understanding how halogens are distributed among usual hydrous silicates in the lithosphere is important to constrain their deep geochemical cycle and fluid-rock interactions subduction zones. This article presents first-principles modelling of halogen (F−, Cl−, Br−) incorporation including mica, chlorite, serpentine, amphibole, epidote carpholite. The approach allows studying impact crystal ch...

[1] In the Inner Basin of the Columbia Hills, Gusev Crater is Home Plate, an 80 m platform of layered clastic rocks of the Barnhill class with microscopic and macroscopic textures, including a bomb sag, suggestive of a phreatomagmatic origin. We present data acquired by the Spirit Mars Exploration Rover by Alpha Particle X-Ray Spectrometer (APXS), Mössbauer Spectrometer, Miniature Thermal Emiss...

Reactive halogen species, released by sea-salt activation, offer a class of reactants of utmost importance for heterogeneous reactions with organic aerosols. To study the interaction of organic aerosols with these halogen species, secondary organic aerosol (SOA) was produced from α-pinene, catechol and guaiacol (Ofner et al., 2011) in a 700 L glass smog-chamber and in a 3500 L Teflon smog-chamb...
