Spectroscopy
The School of Chemistry and Molecular Biosciences offers spectroscopy equipment (Magnetic Circular Dichroism spectroscopy and photochemistry and ultrafast laser spectroscopy) at The University of Queensland's St Lucia campus.
Services
MCD spectroscopy is particularly suitable to the study of transition metal centres where there is a component of unquenched angular momentum. It is used to determine the electronic structure of metal centres, and the coordination/geometry of the metal environment.
Types of experiment
- Linearly and circularly polarised absorption, CD & MCD spectroscopy
- Variable wavelength (300 – 200 nm)
- Variable temperature (1.8 – 300 K)
- Variable magnetic field (0 – 7 Telsa)
Equipment
High resolution Jobin Yvon 750s monochromator and an Oxford Instruments SpectroMag superconducting magnet.

Ultrafast spectroscopy is used to measure the kinetics for a variety of important photophysical processes in chemical and biological research, including electronic structure, photoisomerizations, energy and/or electron transfer, charge transport, optical non-linear effects, and many other processes.
Types of experiment
- Femtosecond transient absorption
- Sub-nanosecond flash photolysis
- Femtosecond Optically Gated (FOG) fluorescence
- Time Correlated Single Photon Counting (TCSPC) lifetimes
Equipment
- 1 kHz 4W amplified Ti:Sapphire laser (Spectra Physics - Spitfire ACE)
- Optical Parametric Amplifier (Light Conversion – Topas Prime)
- Transient Absorption Spectrometer (Ultrafast Systems – HELIOS)
- Time Resolved Fluorescence Spectrometer (Ultrafast Systems – HALCYONE)
