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.
