cata-condensed aromatic hydrocarbons
A large fraction (30 of 62) of the cata-condensed polycyclic benzenoid aromatic hydrocarbons with one to six rings have nonplanar pi carbon atom frameworks, with the minimum angle of nonplanarity approximately 30°. In addition to 17 pairs of enantiomers, four of the nonplanar cata-condensed benzenoids with six rings are redicted to be capable of existing as pairs of twisted diastereoisomers. Ma...
متن کاملDegradation of Aromatic Hydrocarbons
Aromatic hydrocarbons are widely distributed in nature. They are found as lignin components, aromatic amino acids and xenobiotic compounds, among others. Microorganisms, mostly bacteria, degrade an impressive variety of such chemical structures. A broad range of peripheral reactions results in a restricted range of central intermediates, which are subject to ring-cleavage and funneling into the...
متن کاملCapillary Electrochromatography: Polycyclic Aromatic Hydrocarbons
Electrochromatography is utilized to separate a mixture of 16 different polycyclic aromatic hydrocarbons (PAHs). Fused-silica capillary columns ranging in size from 50 to 150 pm i.d. were packed (20-40-cm sections) with 3-pm octadecylsilica particles. A potential of 15-30 kV is applied across the 30-50-cm total length capillary column to generate electroosmotic flow that carries the PAHs throug...
متن کاملPolycyclic aromatic hydrocarbons in carcinogenesis.
A symposium on "Polycyclic Aromatic Hydrocarbons (PAHs) in Carcinogenesis" was presented at the third International Congress of Pathophysiology held in Lathi, Finland, 28 June-3 July 1998. The congress was also sponsored by the International Union of Biological Sciences and the International Society of Free Radical Research. Institutional support for the symposium included the Electric Power Re...
متن کاملDouble Photoionization of Aromatic Hydrocarbons
Electron correlations can be found in various fields of physics whenever we have to go beyond the independent particle model. A convenient method to study electron correlations in gas-phase atoms and molecules is to measure the probability to remove two electrons simultaneously with a single photon (called double photoionization) from the sample. Because a single photon can interact with only o...
