Excited State Dynamics of Dibenzothiophene Derivatives [PDF]

The Journal of Physical Chemistry B, 2023
Polycyclic aromatic sulfur heterocycles are environmental pollutants formed from incomplete combustion processes and crude oil spills. Their excited state dynamics are not understood. Herein, femtosecond transient absorption is combined with steady-state spectroscopy and computational methods to elucidate the relaxation mechanisms of three ...

Probing Excited-State Dynamics of Transmon Ionization

Physical Review X
The fidelity and quantum nondemolition character of the dispersive readout in circuit QED are limited by unwanted transitions to highly excited states at specific photon numbers in the readout resonator.

Excited-State Dynamics of Oxyluciferin in Firefly Luciferase

Journal of the American Chemical Society, 2016
The color variations of light emitted by some natural and mutant luciferases are normally attributed to collective factors referred to as microenvironment effects; however, the exact nature of these interactions between the emitting molecule (oxyluciferin) and the active site remains elusive.

Unveiling the Excited State Dynamics of Indole in Solution. [PDF]

J Chem Theory Comput, 2023
In this paper, we reconstruct in detail the dynamics of the emitting electronic excited state of aqueous indole, investigating its relaxation mechanism and kinetics to be related to the time-dependent fluorescence signal. Taking advantage of the results shown in a very recent paper, we were able to model the relaxation process in solution in terms of ...

Anomalous excited state behaviour of purine tautomers -- an excited dynamics study [PDF]

, 2022
The remarkable photostability of canonical nucleobases makes them ideal building blocks for DNA and RNA. Even minor structural changes are expected to lead to drastic alteration of their sub-picosecond excited state lifetimes.

Excited state dynamics of Zn–salophen complexes [PDF]

Photochemical & Photobiological Sciences, 2022
AbstractZn–salophen complexes are a promising class of fluorescent chemosensors for nucleotides and nucleic acids. We have investigated, by means of steady state UV–Vis, ultrafast transient absorption, fluorescence emission and time dependent density functional theory (TD-DFT) the behavior of the excited states of a salicylidene tetradentate Schiff ...

Excited State Dynamics of 6-Thioguanine [PDF]

The Journal of Physical Chemistry A, 2017
Here we present the excited state dynamics of jet-cooled 6-thioguanine (6-TG), using resonance-enhanced multiphoton ionization (REMPI), IR-UV double resonance spectroscopy, and pump-probe spectroscopy in the nanosecond and picosecond time domains. We report data on two thiol tautomers, which appear to have different excited state dynamics.
