Laser Chemistry Laboratory

The Laser Chemistry Laboratory is engaged in experimental research on reactive molecules (free radicals) and ions in the gas-phase and solution.

Experimental techniques include ion trap mass spectrometry, tunable laser photodissociation spectroscopy and also microdroplet generation and trapping.

We are engaged in the training of undergraduate and postgraduate students – including Honours and PhD level. Our graduates have gone to many sectors including consulting, government, international research labs and education.

July 2017: Josh arrives from Cardiff to start his Masters project on the electrodynamic levitation of microdroplets – studying oxidation on lipid droplets. Welcome Josh.

July 2017: The Laser Chemistry Group attended the ANZSMS meeting in Adelaide – Paddy, Cameron, Sam and Ben all presenting posters. Trevitt presented a talk on the group’s Laser Action Spectroscopy experiments. And Cameron won a best-poster prize. Trevitt was also presented with the ANZSMS Michael Guilhaus Research Award. We are sincerely thankful to ANZSMS and Waters for the award.

Here is a video of a prototype of the experiment related to that award (…yes, that is Blue-Tak on the sides).

Next, Cameron and Trevitt attended the RACI National Congress meeting in Melbourne. Cameron won a best-poster prize … again … for his poster in the Physical Chemistry Division poster session – he’s on fire.

June 2017: Shane Ellis (U Maastricht) and Steve Blanksby (QUT) and others collaborated with our Lab on laser activation of selected lipid ozonides. The paper is now online: https://link.springer.com/article/10.1007/s13361-017-1649-4
