Matrix Isolation Spectroscopic Studies: Thermal and Soft Photochemical Bimolecular Reactions

Abstract: The matrix isolation technique has been a highly effective tool for the study of a wide range of reactive species. This chapter provides an introduction to the technique and to earlier reviews on the topic, followed by a discussion of the basic experimental aspects of matrix isolation. A focus on biomolecular thermal reactions then is presented, from the formation of hydrogen-bonded Lewis acid-base complexes to reactions with low activation barriers. These include the reactions of diborane with electron donors and the ozonolysis of alkenes. An overview of the matrix isolation studies of the reaction of ozone with organometallic compounds relevant to the formation of metal oxide thin films follows. Throughout, twin-jet deposition and merged-jet or flow reactor deposition are contrasted, each having utility for matrix isolation experiments. The application of ab initio and density functional theory calculations to complement the experimental work is also discussed. Finally, the application of “soft” red light irradiation of ozone complexes with a range of substrates to create novel intermediates is described.
