Ion imaging methods are making ever greater impact on studies of gas phase molecular
reaction dynamics. This article traces the evolution of the technique, highlights some of the …

Visualising a collision between an atom or a molecule or a photodissociation (half-collision)
of a molecule on a single particle and single quantum level is like watching the collision of …

The compelling need for standoff detection of hazardous gases and vapor indicators of
explosives has motivated the development of a remotely pumped, high-gain air laser that …

A three-dimensional (3D) ion velocity imaging method was developed to measure the
product velocity distributions in crossed molecular beam experiments. While maintaining …

Chemical reactions at ultracold temperatures are expected to be dominated by quantum
mechanical effects. Although progress towards ultracold chemistry has been made through …

A novel threshold photoelectron-photoion coincidence (TPEPICO) imaging spectrometer at
the U14-A beamline of the Hefei National Synchrotron Radiation Laboratory is presented. A …

Separate coupled-channel Schrödinger-equation (CSE) models of the interacting Π u 1 (b, c,
o) and Π u 3 (C, C′) states of N 2 are combined, through the inclusion of spin-orbit …

Molecular oxygen poses very difficult challenges in molecular photochemistry due to the
extreme weakness of its ultraviolet absorption spectrum. In the past few years a new …

In the late 1980s, Dixon, Hall, Houston, Simons, and others1–6 recognized that experiments
that probe the angular distribution of photofragments with spectroscopic techniques could be …

Photodissociation of singlet oxygen, O2 a1Δg, by ultraviolet radiation in the region from 200
to 240 nm has been investigated using velocity map imaging of the atomic oxygen …
