Molecules as probes of the interstellar medium. It is one of the greatest challenges in Nature is to remotely identify what is in space. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown, implying that there are many more molecules in space than we know about. With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to u ....Molecules as probes of the interstellar medium. It is one of the greatest challenges in Nature is to remotely identify what is in space. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown, implying that there are many more molecules in space than we know about. With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to understand interstellar chemistry. In this project we combine skills in spectroscopy and astronomy to make these molecules in the laboratory, measure their spectra and thereby identify unknown molecules in space.Read moreRead less
Optical Spectroscopy of Extraterrestrial Molecules. Space is not empty. In the vast regions between stars is a complex soup of molecules. Some of these molecules get incorporated into meteorites and find their way to Earth where they can be identified. Analysis has yielded amino acids; the building blocks of life, but these molecules do not match what we know about the interstellar regions. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown. ....Optical Spectroscopy of Extraterrestrial Molecules. Space is not empty.

Analysis has yielded amino acids; the building blocks of life, but these molecules do not match what we know about the interstellar regions. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown. Could they be caused by the missing molecules? In this project we combine the skills of three spectroscopists, each expert in different areas, in an attempt to make these molecules in the laboratory, measure their spectra and thereby identify these unknown molecules that are in space.Read moreRead less
Biomolecular chemical survival strategies of terrestrial extremophiles and the spectroscopic search for life on Mars. This project is aimed to place Australian research at the forefront of developments in the search for extraterrestrial life, the evolution of life on earth, and the design of new probes for the identification of microorganisms.

The research will link key centres in Australia and the UK with international space agencies (NASA and the European Space Agency) in the search for cutting edge techniques to be used in the search for extraterrestrial life forms and their links to paleo and extremophile life forms on Earth.

Roaming around the Transition State: A New Mechanism of Chemical Reactions. Gas-phase reaction mechanisms are at the core of some of the most important problems facing Australia at present: atmospheric models for CO2 are central to climate change; models of isotope exchange are essential to learn about past climates from Antarctic ice cores; and models of combustion are used to optimise energy efficiency. The mechanisms used in these models rely on accurate chemistry. A newly discovered chemica ....Roaming around the Transition State: A New Mechanism of Chemical Reactions. Gas-phase reaction mechanisms are at the core of some of the most important problems facing Australia at present: atmospheric models for CO2 are central to climate change; models of isotope exchange are essential to learn about past climates from Antarctic ice cores; and models of combustion are used to optimise energy efficiency. The mechanisms used in these models rely on accurate chemistry. A newly discovered chemical mechanism has the potential to change many of the reactions that we currently use in these chemical models. This project will determine how important this new mechanism is, and what its impact is on gas-phase reaction models.Read moreRead less
Molecular signatures of complex photodissociation reactions. All energy on earth comes from the sun, either directly (e.g photosynthesis) or indirectly (e.g fossil fuels). Photochemistry is the study of how this light is absorbed and what happens to a molecule afterwards. Despite significant experimental and theoretical advances in the past decade (some in our lab), scientists still cannot predict the outcomes of most photochemical reactions. In this project we will determine the reactivity o ....Molecular signatures of complex photodissociation reactions. All energy on earth comes from the sun, either directly (e.g photosynthesis) or indirectly (e.g fossil fuels). Photochemistry is the study of how this light is absorbed and what happens to a molecule afterwards. Despite significant experimental and theoretical advances in the past decade (some in our lab), scientists still cannot predict the outcomes of most photochemical reactions. In this project we will determine the reactivity of several small, fundamental organic molecules. Not only are these molecules pollutants around our cities, but discovery of how they react in the presence of light will allow us to understand and predict the photochemistry of a much wider range of organic species.Read moreRead less

Photodissociation Dynamics of Radicals and Molecules. Photodissociation dynamics involves studying fundamental chemical processes that underpin all chemical reactivity. We address three of the important unanswered questions in this field: i) how do the lessons learned from small molecules transfer to larger molecules? ii) can one control chemical reactivity by selecting specific states of the reactant?; and iii) are the dynamics of radicals fundamentally different to stable molecules?

We address three of the important unanswered questions in this field: i) how do the lessons learned from small molecules transfer to larger molecules? ii) can one control chemical reactivity by selecting specific states of the reactant?; and iii) are the dynamics of radicals fundamentally different to stable molecules? We will combine expertise in large molecule spectroscopy and photodissociation dynamics with technology in radical production to provide insight into these fundamental questions. Photodissociation dynamics is firmly embedded in photon science and technology.Read moreRead less
