- They are induced by the corticosteroid cortexolone and by phenanthrene . " C . elegans " also possesses a lanosterol 14-alpha demethylase, another enzyme in the cytochrome P450 family.
- This difference in number of sextets is reflected in the UV absorbance spectra of these two isomers; phenanthrene has a highest wavelength absorbance around 290 nm, while anthracene has highest wavelength bands around 380 nm.
- To create such methods, the scientist synthesized the total mellitic acid anhydride, which was found to form orange-red crystals with naphthalene, dark blue with anthracene, brown-red with phenanthrene, and light brown with veratrole.
- The carbene is a tungsten carbonyl when used in stoichiometric amounts ( 1 equivalent ) yields 41 % of the phenanthrene "'3.2 "'and when used in catalytic amounts phenanthrene "'3.3 " '.
- The carbene is a tungsten carbonyl when used in stoichiometric amounts ( 1 equivalent ) yields 41 % of the phenanthrene "'3.2 "'and when used in catalytic amounts phenanthrene "'3.3 " '.
- For example, in phenanthrene one Clar structure has two sextets at the extremities, while the other resonance structure has just one central sextet; therefore in this molecule the outer rings have greater aromatic character whereas the central ring is less aromatic and therefore more reactive.
- For example, " R . glutinis " and " R . rubra " have both been found to have a high ability to degrade phenanthrene, while " R . minuta " has been found to degrade benzo ( a ) anthracene.
- "' Retene "', methyl isopropyl phenanthrene or 1-methyl-7-isopropyl phenanthrene, C 18 H 18, is a polycyclic aromatic hydrocarbon present in the coal tar fraction, boiling above 360 �C . It occurs naturally in the tars obtained by the distillation of resinous woods.

- In addition to lead, coal ash typically contains variable but significant concentrations of polynuclear aromatic hydrocarbons ( PAHs; e . g ., benzo ( a ) anthracene, benzo ( b ) fluoranthene, benzo ( k ) fluoranthene, benzo ( a ) pyrene, indeno ( cd ) pyrene, phenanthrene, anthracene, and others ).
- "Coelogyne cristata " contains coeloginanthridin ( 3, 5, 7-trihydroxy-1, 2-dimethoxy-9, 10-dihydrophenanthrene ), a 9, 10-dihydrophenanthrene derivative, and coeloginanthrin ( 3, 5, 7-trihydroxy-1, 2-dimethoxyphenanthrene ), the corresponding phenanthrene analogue, coelogin and coeloginin.
- Report authors noted that, " emissions of organic substances with potential toxicity to humans and the environment are a major concern surrounding the rapid industrial development in the Athabasca oil sands region ( AOSR ) . " This study found that tailings ponds were an indirect pathway transporting uncontrolled releases of evaporative emissions of three representative polycyclic aromatic hydrocarbon ( PAH ) s ( phenanthrene, pyrene, and benzo ( a ) pyrene ) and that these emissions had been previously unreported.
- BjF can be obtained when either 2-( 1-chloroethenyl ) benzo [ c ] phenanthrene or 6-( 1-chloroethenyl ) chrysene is treated by flash vacuum thermolysis ( FVT ) at high temperatures ( > 900 �C ) followed by ring rearrangements ( ring contraction / expansion ) to selectively yield BjF . benzo [ k ] fluoranthene may also be converted via similar processes to BjF by FVT at temperatures e " 1100 �C ( 6 % yield ) or e " 1200 �C ( 11 % yield ) with 38 % mass recovery.
- Tobacco smoke may be grouped into a particulate phase ( trapped on a glass-fiber pad, and termed " TPM " ( total particulate matter ) ) and a gas / vapor phase ( which passes through such a glass-fiber pad ) . " Tar " is mathematically determined by subtracting the weight of the nicotine and water from the TPM . However, several components of tobacco smoke ( e . g ., hydrogen cyanide, formaldehyde, phenanthrene, and pyrene ) do not fit neatly into this rather arbitrary classification, because they are distributed among the solid, liquid and gaseous phases.
