Imaging CF3I conical intersection and photodissociation dynamics with ultrafast electron diffraction
Science, 2018 Motion picture of a conical intersection In most chemical reactions, electrons move earlier and faster than nuclei. It is therefore common to model reactions by using potential energy surfaces that depict nuclear motion in a particular electronic state ...

Photodissociation of Trapped Rb_{2}^{+}: Implications for Simultaneous Trapping of Atoms and Molecular Ions. [PDF]
Physical Review Letters, 2016 The direct photodissociation of trapped ^{85}Rb_{2}^{+} (rubidium) molecular ions by the cooling light for the ^{85}Rb magneto-optical trap (MOT) is studied, both experimentally and theoretically.

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,

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 ...

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.

Coulomb explosion imaging of CH3I and CH2ClI photodissociation dynamics.
Journal of Chemical Physics, 2018 The photodissociation dynamics of CH3I and CH2ClI at 272 nm were investigated by time-resolved Coulomb explosion imaging, with an intense non-resonant 815 nm probe pulse. Fragment ion momenta over a wide m/z range were recorded simultaneously by coupling

Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions
Angewandte Chemie, EarlyView.This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...
