Laser Chemistry Laboratory

IMG_2217The 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 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.


Nov 2017: Cameron’s first first-author paper is accepted in PCCP – “Highly Efficient Gas-Phase Reactivity of Protonated Pyridine Radicals with Propene” – in collaboration with Blanksby (QUT) and G. da Silva (UMelb). Its online here. Great work Cameron and all.Screen Shot 2017-11-14 at 10.37.28 am.png

Nov 2017: Our three Honours students (Paddy, Ben and Sam) have completed their Honours projects dishing out awesome talks and submitting theses brimming with red-hot data. Great effort – well done.

Also, Boris, our ugrad project student (CHEM340), finished his thesis on the droplet levitation experiment – and presented an excellent talk on his research.

Oct 2017: New JACS Communication is online – awesome collaboration with G. da Silva (UMelb) and Hemberger’s team at Swiss Light Source: link

Sept 2017: The new Laser Chemistry Lab coffee mugs have arrived! Designed by Sam -super effort to get the RRKM theory involved (see the “tight” and “loose” cracks).



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:
