The weak intermolecular interaction between 2,2,2-trifluoroethanol (TFE) and 3-chloro-2-methyl-1propene (CMP) has been investigated by gas phase FTIR spectroscopy and DFT calculations. CMP offers two hydrogen bond docking sites to the hydrogen bond donor: the chlorine atom (O–H/Cl) and the C]C p electron system (O–H/p). DFT calculations suggest that MeOH approaches CMP in five different orienta...

A total of 138 samples o f higher fungi, representing 35 species (15 belonging to the genus Amanita), were analysed for the trace element bromine using spectrophotom etric and gas chromatographic methods. High concentrations o f bromine, up to 100 m g/kg on dry weight, were encountered in Amanitaceae, especially in members o f the subsections Phalloideae and Eu-Amanita, whereas in other fungi t...

Three dimensional model calculations with the NASA/GSFC chemistry and transport model have been designed to consider the impact of heterogeneous processes occurring on polar stratospheric louds (PSC's) in the Arctic vortex on the HC1 distribution. By examining the HC1 concentration for a calculation with PSC's relative to a calculation with gas phase chemistry only, we infer the impact of polar...
