About this collection

We are delighted to share with you a selection of the papers which will be presented at our Faraday Discussion on Advances in ion spectroscopy - from astrophysics to biology taking place in York, UK in April 2019. More information about the event may be found here: http://rsc.li/ionspectroscopy-fd2019. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the live discussions will be published after the event.

Gaseous ion spectroscopy generally couples mass spectrometry with high-resolution laser spectroscopy to studying the intrinsic chemical and physical properties of isolated ions. The isolation of the molecular ion of interest from its native environment is important to decouple the influence of the surroundings from the intrinsic properties. The effect of the environment can then be incrementally re-introduced through studies of sequentially solvated clusters, which allow the interaction with solvent molecules with the ion to be studied on the molecular level. With the potential to impact a wide range of chemical, physical and biological problems, the field has experienced rapid diversification in the past decade with the application of different ion sources, cryogenic ion traps, and new light sources such that this potential impact is rapidly being realised. The rapid development of experimental techniques has required a concomitant development of theory, which is now being used to model ever larger systems both in terms of structure and dynamics. This Faraday Discussion will bring together experimentalists and theoreticians working on ion spectroscopy in a broad sense to discuss the latest innovations and applications mapping the current status and future challenges of this field.
