Photoelectron spectroscopic study of I⁻·ICF₃: a frontside attack S_N2 pre-reaction complex

Abstract

The I−·ICF3 complex, a frontside attack pre-reaction complex of a classic SN2 reaction, is produced and studied using photoelectron spectroscopy.

Role of Nonvalence States in the Ultrafast Dynamics of Isolated Anions

“…2D PE spectroscopy represents the optical analogue of 2D electron energy loss spectroscopy (2D EELS) 51 with the important advantages that PE imaging also provides 2D PADs, [52][53][54]38,40,55 that time-resolved PE imaging can track the dynamics of electron-impact resonances, 53,54,56 and that it enables the study of mass-selected clusters. [57][58][59][60][61]49,62 our early efforts in developing this methodology have been recently reviewed. 63 3.…”

Benchmark ab initio and dynamical characterization of the stationary points of reactive atom + alkane and SN2 potential energy surfaces

“…2 Despite the key role of the stationary points of a reactive PES in chemistry, their experimental investigation is usually highly challenging or even impossible, because the complexes are often unstable and the transition states are not in equilibrium but sit at the top of an energy curve along the reaction coordinate. Some experimental insights can be obtained by advanced matrix isolation 3,4 or anion photo-electron spectroscopy (transitionstate spectroscopy) [5][6][7][8] and crossed-beam scattering, 9,10 but the complete characterization of the stationary points requires theoretical work, which may guide, explain, and complement experiments.…”

Fifty years of nucleophilic substitution in the gas phase

“…Recently the was studied using 2D photoelectron spectroscopy and compared to the earlier work. There the complex was shown to represent the frontside attack with bound to the iodine atom of I (Mensa‐Bonsu et al, 2019).…”
