Abstract Analysis of the 60 Mc/sec proton magnetic resonance spectra of fluoranthene (I), benzo [ k ] fluoranthene (II), and benzo [ ghi ] fluoranthene (III) have been carried out and, for I and II, confirmed at 100 Mc/sec. Differential solvent shifts for the protons helped in the analysis of I and were also observed in III; their presence may imply ...

Bacterial Fluoranthene Degradation
1999During the last fifteen years it became evident that Polycyclic Aromatic Hydrocarbons (PAHs) encompassing more than three rings despite their low water solubility may serve as growth substrates for several kinds of soil bacteria.

Triplet fluoranthenes: Aromaticity versus unpaired electrons
Journal of Molecular Modeling, 2010Three fluoranthenes and one substituted fluoranthene, 2,2-dimethyl-2H-dibenzo[cd,k]fluoranthene, were investigated using the unrestricted symmetry-broken and complete active space methods. It was shown that four Kekuléan hydrocarbons are diradicals, implying that their ground state is a triplet.

Höhere Benzologe des Fluoranthens
Chemische Berichte, 1956AbstractTetrachlortetracen‐dichlorid (I) liefert bei der Friedel‐Craftsschen Reaktion mit Benzol Dichlor‐dibenzfluoranthen (II) neben Di‐o‐phenylen‐tetracen (III), mit Naphthalin in ähnlicher Weise Tribenzfluoranthen (IV) und einen Kohlenwasserstoff der Formel VI oder VII.

Abstract3‐Oxo‐1.2.3.10b‐tetrahydro‐fluoranthen und seine Derivate werden mit Luft in alkalischem Medium zu 3‐Hydroxy‐fluoranthenen aromatisiert. Einige 3‐Hydroxy‐fluoranthene geben Molekülkomplexe mit Fluorenon‐carbonsäure‐(1). Die IR‐Spektren dieser Komplexe und die IR‐Spektren verschiedenfarbiger Fluorenoncarbonsäuren werden diskutiert.
