Abstract Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transition state for thermal reactions and a pericyclic minimum in

We present the design of an electron velocity map imaging (VMI) spectrometer where the ionizing laser source propagates along the symmetry axis of the spectrometer. The co-axial geometry is useful in a variety of experiments, because it provides a un

We present an experimental investigation of symmetry breaking of H_{2} and D_{2} molecules after single photoionization due to the Coulomb field of the emitted slow electron interacting with the parent cation during dissociation. The experiments were

We imaged the conformer-specificity of an electrocyclic ring-opening reaction as predicted by the Woodward-Hoffmann rules in real space and time employing a combination of ultrafast electron diffraction and excited state dynamics simulations.
