Abstract : The accomplished research has centered about the construction of new instrumentation for the investigation of transient high energy materials and the exploration of how the chemistry of transient high energy materials and the dynamics of these species respond to systematic variations in structure, environments, and experimental variables. Particular emphasis has been given to reactions in microheterogeneous environments and interfaces provided by micelles, polymers and porous solids, using resonance Raman spectroscopy, Nuclear magnetic resonance spectroscopy, electron spin resonance spectroscopy, optical absorption and optical emission. The use of external magnetic fields on the reactivity of carbenes, of radical pairs and of biradicals, and of adsorption of reactive intermediates at interfaces has been explored as methods which may be capable of extending the lifetimes of these transient species. Keywords: Micelles; Polymers; Porous solids; Biradicals; Ylides; Carbenes; Radical pairs; Optical absorption; ESR spectroscopy; NMR spectroscopy.
