Equilibrium concentration of singlet oxygen in photoreaction of reaction center/carbon nanotube bionanocomposites

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

The reaction center protein is the unit in the photosynthetic organisms in which the primary events of the photoelectric energy conversion take place during photosynthesis. When the photochemistry following the excitation of the reaction center by light is ...

Synthesis and spectroscopy of anionic tridentate benzimidazole-pyridine carboxylate and tetrazolate chromophore ligands

Svetlana Eliseeva

We report on seven new anionic benzimidazole-pyridine carboxylate and tetrazolate tridentate (NNO)-N-boolean AND-O-boolean AND and (NNN)-N-boolean AND-N-boolean AND ligands that are modified with chromophore (phenyl, biphenyl, naphthyl) and solubilizing gr ...

One-dimensional quantum magnetism in the anhydrous alum KTi(SO4)(2)

Henrik Moodysson Rønnow, Goran Nilsen

The anhydrous alum KTi(SO4)(2), where the Ti3+ (d(1), S = 1/2) ions form an anisotropic triangular lattice, has been prepared by a new hydrothermal route and characterized by magnetic susceptibility and neutron scattering measurements. Contrary to expectat ...

A Vibronic Coupling Hamiltonian to Describe the Ultrafast Excited State Dynamics of a Cu(I)-Phenanthroline Complex

Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Gloria Capano

We present a model Hamiltonian to study the nonadiabatic dynamics of photoexcited Cu(dmp)(2), (dmp = 2,9-dimethyl-1,10-phenanthroline). The relevant normal modes, identified by the magnitude of the first order coupling constants, correspond closely to ...

Fragmentation mechanism of UV-excited peptides in the gas phase

Thomas Rizzo, Oleg Boyarkine, Michael Zachary Kamrath, Aleksandra Zabuga

We present evidence that following near-UV excitation, protonated tyrosine- or phenylalanine–containing peptides undergo intersystem crossing to produce a triplet species. This pathway competes with direct dissociation from the excited electronic state and ...

Dynamics of UV-excited, protonated peptides in the gas phase

Aleksandra Zabuga

The scope of this thesis is the electronically excited state dynamics of protonated peptides and their photofragmentation mechanism. UV radiation induces fragmentation of biological molecules and might cause various diseases, such as cataracts or skin canc ...

Photobleaching Kinetics and Time-Integrated Emission of Fluorescent Probes in Cellular Membranes

Daniel Sage

Since the pioneering work of Hirschfeld, it is known that time-integrated emission (TiEm) of a fluorophore is independent of fluorescence quantum yield and illumination intensity. Practical implementation of this important result for determining exact prob ...
