Time-resolved studies with FELs [PDF]
Journal of Electron Spectroscopy and Related Phenomena, 2015 Abstract Intense femtosecond VUV, XUV, and X-ray pulses from free-electron lasers (FELs) enable time-resolved experiments studying ultrafast dynamics in a large variety of systems relevant, e.g., to physics, chemistry, biology, and material sciences.

Time-Resolved Infrared (TRIR) Studies of Oxycarbonylnitrenes
The Journal of Organic Chemistry, 2016 N-Ethyloxycarbonyl-S,S-dibenzothiphene sulfilimine and N-t-butyloxycarbonyl-S,S-dibenzothiphene sulfilimine have been utilized as precursors to ethoxycarbonylnitrene and t-butyloxycarbonylnitrene. B3LYP/6-31G(d) calculations predict triplet ground states for both oxycarbonylnitrenes, albeit by small margins.

Time-Resolved Studies of Protein Structural Dynamics
Proteins change their conformations in a sophisticated manner when they perform their functions. Time-resolved serial femtosecond crystallography is a potent tool for determining protein dynamic structures.

Time-resolved photoluminescence study of SiAg [PDF]
Physica B: Condensed Matter, 2001 Abstract Photoluminescence band at 780 meV , previously assigned to silver-related centers in Si on basis of indirect arguments, is investigated in detail. For that purpose specially prepared samples doped with isotopically enriched silver are used.

Time-resolved study of the photodissociation of Au2O− [PDF]
Chemical Physics Letters, 2007 Photodissociation of the Au2Oanion following absorption of a 3.1 eV photon is studied using time-resolved photoelectron spectro- scopy. A new spectral feature appearing after 1 ps indicates the existence of a long-lived excited state with a geometry different from that of the ground state.

Time-resolved studies of light propagation in paper [PDF]
Applied Optics, 1995 A method for time-resolved recording of light scattering in thin, highly scattering media is described. Subpicosecond pulses from a high-power Ti:sapphire laser are used, and single-shot recordings of the scattered light are made with a fast streak camera.

Time-Resolved Study of Thymine Dimer Formation [PDF]
Journal of the American Chemical Society, 2005 The formation of thymine dimers in the single-stranded oligonucleotide, (dT)20, is studied at room temperature by laser flash photolysis using 266 nm excitation. It is shown that the (6-4) adduct is formed within 4 ms via a reactive intermediate. The formation of cyclobutane dimers is faster than 200 ns.

Nanosecond X-ray photon correlation spectroscopy using pulse time structure of a storage-ring source
IUCrJ, 2021 X-ray photon correlation spectroscopy (XPCS) is a routine technique to study slow dynamics in complex systems at storage-ring sources. Achieving nanosecond time resolution with the conventional XPCS technique is, however, still an experimentally ...

Time‐resolved NMR studies of RNA folding [PDF]
Biopolymers, 2007 AbstractThe application of real‐time NMR experiments to the study of RNA folding, as reviewed in this article, is relatively new. For many RNA folding events, current investigations suggest that the time scales are in the second to minute regime.
