Slow electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI) is a high-
resolution variant of anion photoelectron spectroscopy that has been applied with …

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

Reaction pathways that bypass the conventional saddle-point transition state (TS) are of
considerable interest and importance. An example of such a pathway, termed “roaming,” has …

The potential energy surface for the reaction between OH and acetylene has been
calculated using the RQCISD (T) method and extrapolated to the complete basis-set limit …

High-resolution photoelectron spectra of vibrationally pre-excited vinoxide anions (CH2CHO–

Using multireference configuration interaction expansions comprised of over 7 million
configuration state functions, three-state conical intersections are reported for the closely …

The reaction of O (3 P) with C 2 H 4, of importance in combustion and atmospheric
chemistry, stands out as paradigm reaction involving not only the indicated triplet state …

The potential in the vicinity of the stationary points on the surface for the decomposition of
ground-state vinoxy and acetyl radicals has been calculated using the RQCISD (T) method …

An efficient algorithm for locating conical intersections of three states of the same symmetry
is presented. The algorithm, which derives its efficiency from the use of analytic gradient …

The long-range electronic structure of polyanions is defined by the repulsive Coulomb
barrier (RCB). Excited states can decay by resonant electron tunnelling through RCBs, but …
