Argon matrix samples of Kr/F2, Xe/F2, Xe/Cl2, and Xe/Br2 have been photolyzed at 20 K. Emission spectra using uv excitation absorption following photolysis are assigned to the KrF, XeF, XeCl, XeBr molecules. Vibrational spacings on two KrF XeF bands near RbF CsF values, which supports ionic model for excited states. The vibronic absorptions, very sharp XeCl bands, indicate ground state potential function minima values. This suggests that chemical bonding effects significant in XeCl.
Organosulfates formed from heterogeneous reactions of organic-derived oxidation products with sulfate ions can account for >15% secondary organic aerosol (SOA) mass, primarily in submicron particles long atmospheric lifetimes. However, fundamental understanding organosulfate molecular structures is limited, particularly at atmospherically relevant acidities (pH = 0-6). Herein, 2-methyltetrol sulfates (2-MTSs), an important group isoprene-derived organosulfates, protonation state and...
Argon matrix samples containing O2 and Cl2 have been bombarded with 2.0 keV protons deuterons during condensation at 15°K. In the oxygen experiments, bands due to O3 HO2 appeared. Of most interest is isolated O−3 804.3 cm−1. Deuteron radiolysis produced increased yields of 644 cm−1 band which confirmed as a DAr+n species. Proton deuteron chlorine−containing HCl2x DCl2x in high yields. Owing strong electron scavenging capability chlorine, these species are probably anions.
