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

Summary
Electrochemical Electron Spin Resonance Spectrometer. Electron Spin Resonance Spectroscopy (ESR), is a technique used to determine the presence of free unpaired electrons in a sample. Detection and life time studies of radical species is critical to understanding the mechanisms involved in chemical reaction, sample degradation, performance upon exposure to light and oxidation or reduction processes. Combining ESR with an electrochemical interface permits in-situ studies on how electrons are inje ....Electrochemical Electron Spin Resonance Spectrometer. Electron Spin Resonance Spectroscopy (ESR), is a technique used to determine the presence of free unpaired electrons in a sample. Detection and life time studies of radical species is critical to understanding the mechanisms involved in chemical reaction, sample degradation, performance upon exposure to light and oxidation or reduction processes. Combining ESR with an electrochemical interface permits in-situ studies on how electrons are injected or removed from a sample, providing fundamental information on the processes occurring within the sample. Applications will be in the area of electrofunctional materials, complex biomolecular reactions, organic photovoltaics and new materials for nerve cell regeneration.Read moreRead less
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

Australian Synchrotron Sciences Network. A synchrotron light source is a critical piece of infrastructure for a modern technological nation. In 2001, the Victorian government announced that it would contribute $157M towards the establishment of a national synchrotron facility, becoming operational in 2007. The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users.

The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users. A vibrant and productive facility requires a transparent interface between the scientist and the technology. This Network will set up the communication channels within the user base, and between the users and the facility development program.Read moreRead less

Laser Spectroscopy of Molecular Electronic Components. Electronic devices such as computer memory have been getting smaller and smaller for decades, yet soon devices will need to be constructed from single molecules. Single molecules behave very differently to copper conductors and silicon chips.
