Influence of excited-state absorption on time-resolved luminescence: general formalism and application to the phosphorescence of polycyclic aromatic hydrocarbons.
ChemPhysChem 16(3) , 640-8, (2015) The luminescence decay of a species in an absorbing medium whose optical thickness changes with time, as occurs with triplet-triplet absorption following excitation cut-off, is studied theoretically and experimentally. A general luminescence decay function ba... |

Raman and ROA spectra of (-)- and (+)-2-Br-hexahelicene: experimental and DFT studies of a π-conjugated chiral system.
J. Phys. Chem. B 117(7) , 2221-30, (2013) The Raman optical activity (ROA) spectra of both enantiomers of 2-Br-hexahelicene in chloroform solution have been measured in the range 1700-300 cm(-1). Density functional theory (DFT) calculations accurately reproduce the observed features. The most intense... |

Electric field polarization in conventional density functional theory: from quasilinear to two-dimensional and three-dimensional extended systems.
J. Chem. Phys. 135(15) , 154101, (2011) The large overshoot in (hyper)polarizabilities of quasilinear (1D) chains calculated by applying density functional theory with conventional functionals is investigated for several 2D and 3D extended systems. These systems include arrays of molecular hydrogen... |

Exposure to dust-bound PAHs and associated carcinogenic risk in primitive and traditional cooking practices in Pakistan.
Environ. Sci. Pollut. Res. Int. 22 , 12644-54, (2015) The aim of this study was to determine the abundance and distribution of polycyclic aromatic hydrocarbons (PAHs) in dust samples collected from the selected professional cooking workplaces (WCs) and residential household cooking areas (WRs), where traditional... |

Source, profile, and carcinogenic risk assessment for cohorts occupationally exposed to dust-bound PAHs in Lahore and Rawalpindi cities (Punjab province, Pakistan).
Environ. Sci. Pollut. Res. Int. 22 , 10580-91, (2015) In this study, the occurrence and concentrations of PAHs in dust samples, which were collected from the traffic police cabins/working spots, located on the main busy roads of Lahore (TP-L) and Rawalpindi (TP-R) cities (Punjab province, Pakistan) and from the ... |

A benchmark comparison of σ/σ and π/π dispersion: the dimers of naphthalene and decalin, and coronene and perhydrocoronene.
J. Am. Chem. Soc. 134(42) , 17520-5, (2012) The stacking interaction between π systems is a well-recognized structural motif, but stacking between σ systems was long considered of secondary importance. A recent paper points out that σ stacking can reach the energy of chemical bonds and concludes that "... |

Asphaltene detection using surface enhanced Raman scattering (SERS).
Chem. Commun. (Camb.) 51(33) , 7152-5, (2015) Surface enhanced Raman spectroscopy using a gold substrate and excitation at 514 nm can detect sub parts per million quantities of asphaltene and thereby petroleum. This simple format and sensitivity make it transformative for applications including sample tr... |

Ions interacting with planar aromatic molecules: modeling electron transfer reactions.
J. Chem. Phys. 138(5) , 054306, (2013) We present theoretical absolute charge exchange cross sections for multiply charged cations interacting with the Polycyclic Aromatic Hydrocarbon (PAH) molecules pyrene C(14)H(10), coronene C(24)H(12), or circumcoronene C(54)H(18). These planar, nearly circula... |

Can Coronene and/or Benzo(a)pyrene/Coronene ratio act as unique markers for vehicle emission?
Environ. Pollut. 184 , 650-3, (2014) Coronene is a high molecular weight polycyclic aromatic hydrocarbon with seven aromatic rings. It, more specifically a lower ratio of Benzo[a]pyrene to Coronone (BaP/COR), is suggested as a marker for vehicle emission. In the present study, emissions of Coron... |
