A velocity map imaging study
A study of the photodissociation dynamics of NO2 in the 200–205 nm region using resonance enhanced multiphoton ionization (REMPI) in conjunction with the velocity map imaging technique is presented. We chose this region because it allowed the use of a single laser to photodissociate the NO2 molecule and probe both the O(D2) fragment using (2+1) REMPI via the 3p ′1P1 state at 2× 205.47 nm and th...
متن کاملSliced space - filling designs
We propose an approach to constructing a new type of design, a sliced space-filling design, intended for computer experiments with qualitative and quantitative factors. The approach starts with constructing a Latin hypercube design based on a special orthogonal array for the quantitative factors and then partitions the design into groups corresponding to different level combinations of the qual...
متن کاملSlow electron velocity-map imaging of negative ions: applications to spectroscopy and dynamics.
Anion photoelectron spectroscopy (PES) has become one of the most versatile techniques in chemical physics. This article briefly reviews the history of anion PES and some of its applications. It describes efforts to improve the resolution of this technique, including anion zero electron kinetic energy (ZEKE) and the recently developed method of slow electron velocity-map imaging (SEVI). Applica...
متن کاملSlow electron velocity-map imaging spectroscopy of the C4H- and C4D- anions.
High resolution photodetachment spectra of C4H- and C4D- obtained via slow electron velocity-map imaging (SEVI) are presented. The spectra reveal closely spaced transitions to the neutral 2Sigma+ and 2Pi states which can be distinguished based on the corresponding photoelectron angular distributions. The C4H ground state is confirmed as the X2Sigma+ state, with the excited A2Pi state lying only...
متن کاملVibronic structure in C2H and C2D from anion slow electron velocity-map imaging spectroscopy.
The C2H and C2D radicals are investigated by slow electron velocity-map imaging (SEVI) of the corresponding anions. This technique offers considerably higher resolution (<0.5 meV) than photoelectron spectroscopy. As a result, SEVI spectra of the two isotopomers yield improved electron affinities and reveal many new structures that are particularly sensitive to vibronic coupling between the grou...
