Summary on Grant Application Form
Inorganic chemistry is traditional undertaken in the condensed phase for one very simple reason: very few inorganic compounds are sufficiently volatile as to provide any material in the gas phase. However, some aspects of condensed phase chemistry have distinct disadvantages. Frequent collisions lead to some metal - molecule combinations being unstable. Coisions also have an effect on the spectroscopy of compounds, and low temperatures are often used to improve resolution. Finally, compounds that consist of a (positively) charged metal ion are prepared in the presence of a (negatively charged) counter ion, and the latter can have an influence on the structure and spectroscopy of the metal-containing component. The intention in this proposal is to pursue the study of a select group of inorganic complexes in the gas phase. A combination of theory and experiment will investigate the nature of the metal - molecule interaction free from the constraints identified above. Preliminary experiments have already demonstrated that, when free to coordinate water molecules in the absence of any boundaries, the primary metal ion - solvent structure is quite different from that predicted from experiments performed in the condensed phase. When studied in complete isolation, the only forces responsible for the properties exhibited by the complexes are those that are fundamental to bonding and structure. Once we can establish a particular property by experiment - theory will place that observation in the context of a model for a particular complex that will reveal details of the important interactions responsible structure and stability. Systems to be studied range from the very simple where, for example, metal ions will be bound to water molecules, through to attempts to develop model bioinorganic structures.
