Welcome! Here you will find a few photos and bits of information on some of the projects I’ve been working on lately. Hopefully you’ll find this work as interesting as I do!
Paper describing the 2D spectrometer design was published in The Journal of Physical Chemistry A (DOI: 10.1021/acs.jpca.0c00285). The accepted version of the manuscript can be downloaded here, along with the supporting information.
Our Millennia Prime stopped working, tripping the circuit breakers. I’m hoping it’s just power supply issues, and it’s out of warranty, so let’s take a look. Just don’t think about how much this thing costs… Getting to the power supply unit doesn’t look like fun… It is mounted on the bottom left, underneath a couple …
Here is a quick rundown on how the delay stages are calibrated to relate the rotation angle to the delay time of the laser pulse. An interferometer is built by inserting a mirror/beamsplitter combination after the delays to interfere pairs of the four beams. A Helium-Neon (HeNe) laser is used as the light source, as …
My name is Patrick Tapping. I’m currently working as an ARC Research Associate in the Department of Chemistry at The University of Adelaide, Australia. My home is in the laser spectroscopy lab under Associate Professor Tak W. Kee. Our research group uses ultrafast laser spectroscopy to study how materials absorb light, produce excited states, and transport that energy, with a focus on organic photovoltaic applications.
My current project is the construction of a two-dimensional electronic spectrometer. This involves all the optics and hardware layout as well as development of the software to drive it and collect data.
I obtained my Ph.D in Chemistry in 2016 with a thesis entitled Theoretical and Spectroscopic Studies of Energy and Charge Transport in Organic Semiconductors, supervised by Tak W. Kee and David M. Huang. Chapters included spectroscopic studies of conjugated polymers, simulations of energy transport through conjugated polymer systems, and quantum mechanical modelling of singlet exciton fission/triplet fusion processes in molecular systems.
My bachelor’s degree majored in chemistry and computer science. I’ve always enjoyed programming, so it’s great to be able to use my programming and data analysis skills for such interesting physical chemistry applications.
