Halogen···Halogen interactions in host - guest systems
For a few decades now, halogen bonds which are non-covalent interactions, have gained a lot of interest in the science community due to their applications in diverse research areas. Halogen bonding (XB) is an interaction that occurs between electron deficient halogen compounds and electron donors. …

Halogen-, Azid- und Koordinationsverbindungen des Phosphors
… •= Es konnte gezeigt werden, daß die Phosphortrihalogenide PCl3, PBr3, PI3 und P2I4 wie auch die Phosphor-Chalkogenide P4S3 und P4Se3 aufgrund ihrer schwachen Donoreigenschaft nur sehr schwachgebundene Spezies mit Elektronenacceptoren bilden. So sind die gebildeten Komplexverbindungen X3P⋅BY3 (X …

Satellite Observations of Atmospheric Halogen Oxides
Die große Bedeutung von Halogenverbindungen bezüglich der Zerstörung atmosphärischen Ozons wurde schlagartig offenbar, als Mitte der Achtziger Jahre ein dramatischer Ozonverlust über der Antarktis beobachtet wurde, seither bekannt als Ozonloch. Während der folgenden Jahre konnten reaktive …

Organic particle formation in halogen-influenced environments
… the reaction of organic trace gases and reactive halogen species can act as an important natural source of organic aerosol. In order to better understand these reactions, aerosol formation from the reaction of α-pinene with chlorine and bromine was studied in laboratory experiments. New particle …

Reactions of aluminum with halogen containing oxides
… in an unconfined environment. In particular, halogen based formulations such as aluminum and iodine pentoxide have received significant attention due to both high flame speeds and biocidal properties. Studies have attributed high flame speeds to convective influences within a reaction driving …

Photo-Assisted Etching in Halogen Containing Plasmas
… etching (PAE) was studied in various halogen containing plasmas. Cl2, Br2, HBr, Br2/Cl2, and HBr/Cl2 feed gases diluted in Ar (50%–50% by volume) were used to study etching of p-type Si(100) in a radio frequency, inductively coupled, Faraday-shielded plasma. PAE was observed in all …

Halogen Oxides in the Mid-Latitudinal Planetary Boundary Layer
Die Bedeutung reaktiver Halogenverbindungen (RHS) in der Troposphäre ist durch plötzlich auftretende, sehr schnell ablaufende Ozoneinbrüche während des polaren Sonnenaufgangs dokumentiert. Ob RHS jedoch auch in mittleren Breiten signifikante Auswirkungen auf die Chemie der Troposphäre haben, war …
