Nanosecond time-resolved IR study of thiobenzoylnitrene
Physical Chemistry Chemical Physics, 2012Nanosecond time-resolved infrared (TRIR) spectroscopy has been used to observe singlet thiobenzoylnitrene at 1740 cm(-1) upon photolysis of 5-phenyl-1,2,3,4-thiatriazole in acetonitrile and dichloromethane. Consistent with the experimental observations, thiobenzoylnitrene is predicted by B3LYP/6-31G* calculations to have a singlet ground state with an ...

Stain Effects Studied by Time-Resolved Infrared Imaging
Analytical Chemistry, 2008Pattern formation in evaporating colloidal droplets is an important phenomenon that is commonly observed in several solute-solvent systems; this is also an emerging technique for obtaining fine patterning through controlled conditions of drying. After evaporation of the solvent a ring-like pattern remains on the solid substrate under the condition of ...

Time-resolved X-ray scattering studies of proteins
Current Opinion in Structural Biology, 2021Time-resolved small- and wide-angle X-ray scattering studies of proteins in solution based on the pump-probe approach unveil structural information from intermediates over a broad range of length and time scales. In spite of the promise of this methodology, only a fraction of the wealth of information encoded in scattering data has been extracted in ...

Time-resolved photoluminescence study of InSe
Solid State Communications, 1985Time-resolved photoluminescence spectra of InSe at superfluid He temperatures show that one broad luminescence feature centred at 1315meV is due to donor-acceptor pair recombination whereas other, lower energy broad bands are not. The sharp lines around 1333meV were identified as bound exciton luminescence from their transient behaviour.

A Time-Resolved Spectroscopic Study on Peptide Folding
2010Generation of nucleation centers, such as the helix-turn-helix motif, is one of the possible mechanisms of protein folding. Therefore, knowledge of the kinetics of formation of such locally structured domains may be important for discriminating different folding pathways.

Time resolved crystallographic studies [PDF]
, 2010 X-ray crystallography is an important analytical method for the characterisation of materials in the solid state. During the last decade, it has become important as a tool in the new field of photocrystallography. This combines both crystallography and photochemistry and is used to monitor the formation of light-induced metastable and transient species,

Time Resolved Studies Of Adsorbed Species
SPIE Proceedings, 1985A time-resolved Fourier transform IR study of ethyne adsorbed on ZnNaA zeolite yields results very different from those reported for related systems. Initially two species (A and B) are formed by the interaction of C2H2 with the cations. Whereas species A (π-bonded C2H2) was found to be removed immediately on evacuation, species B (probably Zn ...

Laue crystallography: time-resolved studies
2006The term ‘Laue diffraction’ describes the process of X-ray scattering that occurs when a stationary crystal is illuminated by a polychromatic beam of X-rays. Recent developments in Laue diffraction have depended on three main advances: the use of very intense polychromatic synchrotron sources; the realization that the so-called energy-overlap or ...

Conformation of parathyroid hormone: time-resolved fluorescence studies
Biochemistry, 1992Conformational and environmental changes in the functionally significant amino-terminal region of human parathyroid hormone (hPTH), induced by solvent or by complexation with acidic lipid, have been investigated. Structural perturbations were monitored by their effect on the fluorescence decay kinetics of the single tryptophyl residue at position 23 ...
