Roaming reactions were first clearly identified in photodissociation of formaldehyde 15 years
ago, and roaming dynamics are now recognized as a universal aspect of chemical reactivity …

The phenomenon of roaming in chemical reactions has now become both commonly
observed in experiment and extensively supported by theory and simulations. Roaming …

Since the discovery of roaming as an alternative molecular dissociation pathway in
formaldehyde (H2CO), it has been indirectly observed in numerous molecules. The …

The roaming chemical reaction mechanism involves near-dissociation of an energized
molecule to radicals that leads instead to intramolecular reaction after reorientation at long …

Since its discovery 16 years ago, roaming has become a ubiquitous mechanism in
molecular photochemistry. Its general features are now understood, but little detail is known …

A method for fitting ab initio determined spin–orbit coupling interactions, in the Breit–Pauli
approximation, based on quasidiabatic representations using neural network fits is reported …

Photodissociation studies in molecular beams that employ position-sensitive particle
detection to map product recoil velocities emerged thirty years ago and continue to evolve …

The effect of the incident UV pump wavelength on the subsequent excited state dynamics,
electronic relaxation, and ultimate dissociation of formaldehyde is studied using first …

The first experimental observation of the primary photochemical channel of acetaldehyde
leading to the formation of ketene (CH2CO) and hydrogen (H2) molecular products is …

A new approach for preventing zero-point energy (ZPE) violation in quasi-classical trajectory
(QCT) simulations is presented and applied to H 2 CO “roaming” reactions. Zero-point …
