I’m now officially a H-atomer. I’m lucky to have worked with Drs. Marchetti and Karsili on a study of 2- and 3-substituted thiophenols using the famous Bristol H Rydberg atom PTS. The first study to press since I rebuilt and resuscitated the rig in 2016.

I’ve been selected to give an oral presentation for the Spectroscopy & Dynamics Group at the inaugural Faraday Joint Interest Group meeting to be held 11-13 April 2017 in Warwick.

The UV photodissociation of 2-bromothiophene was the first study to make it to press from the Bristol velocity-map imaging (VMI) rig since being overhauled for multi-mass VMI and universal detection. Accepted a mere 16 days after submission, this invited paper will soon appear online in a Special Topic Issue of J. Chem. Phys. focusing on “Developments and Applications of Velocity Mapped Imaging Techniques”. Stay tuned.

I’ve returned from a week of free electron laser beamtime at the Deutsches Elektronen-Synchrotron in Hamburg. My colleague from Bristol, Rebecca Ingle, and I contributed to a collaboration spanning the globe and committed to unambiguously characterising ring-opening photochemistry in the gas-phase.

I’ve just returned from the annual meeting of the Southern Universities RSC Spectroscopy and Dynamics group at Nottingham University over the 22nd-23rd of September where I presented a talk on multimass VMI using the PImMS camera. I’ll be organising the 2017 annual meeting to be hosted by the University of Bristol.

We come to the end of a fruitful meeting of the Oxford and Bristol Chemical Dynamics groups hosted at Bristol and coordinated by myself. A lot of productive discussion followed short talks on the joint EPSRC Programme Grant activities. See many of you in two days time at SUSDG!

The strongest experimentally-observed gas-phase base has been reported in Chemical Science. The result of an exciting collaboration spanning the University of Wollongong, Queensland University of Technology, Australian
National University and University of Sydney.

Protonated retinal Schiff base decomposes in solution to yield an ion 2 Da lighter. Hansen and Trevitt (Wollongong) collaborated on a study lead by Coughlan and Bieske and coworkers (Melbourne) to identify and characterise this decomposition product using ion mobility spectrometry, photoisomerisation action spectroscopy and collision induced dissociation mass spectrometry. The article has just appeared online in the Journal of the American Society for Mass Spectrometry.
