Photodissociation Dynamics of DNA Bases [PDF]

Journal of Biological Physics, 2003
In order to access the damaging mechanismsof DNA and its bases on themolecular level by T Hz radiation, it isnecessary to create a database of assessingdamage at different spectral regions.Possible damage by T Hz radiation will beassessed by comparison.

Fabrication of Superhydrophobic Silicone Rubber with Periodic Micro/Nano-Suction Cup Structure by ArF Excimer Laser-Induced Photodissociation

Nanomaterials, 2019
A 193-nm ArF excimer laser was used to induce the photodissociation of Si–O bonds of silicone rubber in order to fabricate a periodic micro/nano-suction cup silicone structure, approximately 1 μm in diameter and 2 μm in height at regular intervals of 2.5

Time-resolved X-ray photoelectron spectroscopy: ultrafast dynamics in CS2 probed at the S 2p edge [PDF]

, 2023
Recent developments in X-ray free-electron lasers have enabled a novel site-selective probe of coupled nuclear and electronic dynamics in photoexcited molecules, time-resolved X-ray photoelectron spectroscopy (TRXPS).

Vibrationally mediated photodissociation dynamics of pyrrole

AIP Advances, 2019
We investigate photodissociation of vibrationally excited pyrrole molecules in a velocity map imaging experiment with IR excitation of N–H bond stretching vibration v1 = 1, νIR= 3532 cm−1, and UV photodissociation at λUV= 243 nm. In the IR+UV experiment,

Experimental Study of the Laser-Induced Oxyhemoglobin Photodissociation in Cutaneous Blood Vessels

Acta Medica Bulgarica, 2015
A new optical method for reduction of local tissue hypoxia is proposed. It is shown that this method of phototherapy allows the control of a local oxygen concentration in tissue.

Jitter-correction for IR/UV-XUV pump-probe experiments at the FLASH free-electron laser

New Journal of Physics, 2017
In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can

Photodestruction of Diatomic Molecular Ions: Laboratory and Astrophysical Application

Molecules, 2020
In this work, the processes of photodissociation of some diatomic molecular ions are investigated. The partial photodissociation cross-sections for the individual rovibrational states of the diatomic molecular ions, which involves alkali metals, as well ...
