Scientists have now measured differential cross sections (DCSs) for the reaction H + D2 -> HD + D, which has enabled them to fill many of the gaps in our basic understanding of chemical reactivity.
Differential cross sections for H + D2 → HD(v′ = 2, j′ = 0,3,6,9) + D at center-of-mass collision energies of 1.25, 1.61, and 1.97 eV

Scientists have pinpointed the moment that the CO bond, the strongest bond of any diatomic molecule, breaks when oxidised by a gold catalyst.
Until now, research has only focussed on the catalysts’ active site and not on the reaction mechanisms. Graham Hutchings, Albert Carley and colleagues at the University of Cardiff have investigated the reaction mechanism occurring on a Au/Fe2O3 catalyst and found that CO dissociates at ambient temperature when co-adsorbed with O2.
‘The oxidation of CO gives a surprising result on a gold catalyst as the CO bond being broken is counter-intuitive since it is the strongest diatomic bond,’ says Hutchings.

PCCP is pleased to announce a high-profile themed issue on multiply charged ions (MCIs) in the gas-phase, Guest Edited by Professor Stephen Price (University College London) and Dr Jana Roithová (Charles University, Prague).
Submit to this themed issue – Submission Deadline: 16 May 2011
Fifteen years ago gas-phase multiply-charged ions (MCIs) were viewed as chemical oddities. However, the development of a wide variety of new experimental and theoretical methodologies now means that the unique and unusual properties of these species (both negatively and positively charged) have begun to be revealed: from reactions forming new dicationic rare gas compounds to supramolecular assembly of multiply-charged species in a mass spectrometer.
Our increased understanding of the properties of MCIs allows us to appreciate that their chemistry may be involved in media as varied as fusion plasmas and planetary ionospheres. Scientists are now working on vast range of MCI projects, yet these seemingly rather disparate fields are united because, in all cases, the properties of the MCIs are critically determined by the subtle competition of electrostatic repulsion and chemical bonding.
This issue will highlight the parallel progress and common themes in the chemical physics and physical chemistry of MCIs. The varied topics covered will generate an issue which will appeal to the broad spread of scientists involved with gas-phase MCIs: molecular and chemical physicists, spectroscopists and mass spectrometrists, physical chemists and even inorganic chemists.
