Deciphering the internal conversion and triplet formation in thymine via time-resolved multi-center X-ray photoelectron spectroscopy
Xiaojun Wang, Woojin Park, Dennis Mayer +12
The photostability of DNA nucleobases relies on ultrafast nonradiative relaxation following ultraviolet excitation. In thymine, the competition between internal conversion (IC) and…
Ultrafast photo-ion probing of the relaxation dynamics in 2-thiouracil
Matthew S. Robinson, Mario Niebuhr, Markus Gühr
In this work we investigate the relaxation processes of 2-thiouracil after UV photoexcitation to the S2 state through the use of ultrafast, single-color, pump-probe UV/UV spectrosc…
Transient Resonant Auger-Meitner Spectra of Photoexcited Thymine
Thomas J. A. Wolf, Alexander C. Paul, Sarai D. Folkestad +15
We present the first investigation of excited state dynamics by resonant Auger-Meitner spectroscopy (also known as resonant Auger spectroscopy) using the nucleobase thymine as an e…
Imaging the Photochemical Ring-Opening of 1,3-Cyclohexadiene by Ultrafast Electron Diffraction
T. J. A. Wolf, D. M. Sanchez, J. Yang +20
The ultrafast photoinduced ring-opening of 1,3-cyclohexadiene constitutes a textbook example of electrocyclic reactions in organic chemistry and a model for photobiological reactio…
Probing ultrafast ππ*/nπ* internal conversion in organic chromophores via K-edge resonant absorption
T. J. A. Wolf, R. H. Myhre, J. P. Cryan +21
Organic chromophores with heteroatoms possess an important excited state relaxation channel from an optically allowed ππ* to a dark nπ*state. We exploit the element and site specif…
