On the Fluorescence Quenching of Polycyclic Aromatic Hydrocarbons by Nitromethane
Fluorescence quenching of 22 polycyclic aromatic hydrocarbons by nitromethane in toluene and acetonitrile solutions has been studied. Contrary to Sawicki's observations that the fluorescence of hydrocarbons with the fluoranthene skeleton is not quenched that of 11J2and 3.4-benzofluoranthene and fluoranthene itself is quenched. These compounds have a high energy of the fluorescence transition. T...
متن کاملCoupling between dipole-bound and valence states: the nitromethane anion
Nitromethane is a prototypical example for a molecule that can bind an extra electron in two fundamentally different ways forming dipole-bound as well as valence anions. The classification of the electronic states as dipole-bound or valence does in fact suggest a diabatic viewpoint, and we investigate the coupling between these two electronic states of the nitromethane anion. The coupling eleme...
متن کاملMINDO-Forces Study on Substituted Nitromethane aci-Nitromethane Tautomerism
MINDO-Forces calculations with complete geometry optimization have been performed on nitromethane, aci-nitromethane and X-substituted nitromethane and aci-nitromethane (X = F, OH, NH2, CH3, CN, CF3, NO2, CHO). It is found that nitromethane is more stable than aci-nitromethane by 9.337 kcal/mol. This agrees with theoretical calculations. Thermodynamically, substituted acinitro tautomers are more...
متن کاملThree-way analysis of fluorescence spectra of polycyclic aromatic hydrocarbons with quenching by nitromethane.
The application of trilinear decomposition (TLD) to the analysis of fluorescence excitation-emission matrices of mixtures of polycyclic aromatic hydrocarbons (PAHs) is described. The variables constituting the third-order tensor are excitation wavelength, emission wavelength, and concentration of a fluorescence quencher (nitromethane). The addition of a quencher to PAH mixtures selectively redu...
متن کاملNitromethane - Methyl Nitrite Rearrangement: The Seising of Discrepancy between Theory and Experiment
The potential energy hyper surfaces (FES) of the unimolecular rearrangements of a) Nitromethane itei totrans acknitromethane b) nitrometharie (/) to methyl nitrite (3) and c) naromethane decomposition tomethyl and nitrogen dioxide were searched using the ab !nth° MP2 method. Split valence 6-310(d.p) basisset was used for geometry optimizations, frequency and 1RC computations along each reaction...
