Research during the last three years has focused on using negative ion photoelectron (PE) spectroscopy and zero electron
kinetic energy (ZEKE) spectroscopy to probe the effects of clustering on the energetics, spectroscopy, and dynamics of ions
and transition states, and to investigate the ground and excited electronic states of reactive free radicals. We have also
developed a new spectroscopic method in which stimulated Raman pumping combined with PE spectroscopy is used to
measure vibrational frequencies in negative ions. Results are summarized in more detail below.

The objective of the research is to identify, develop and transition new propellants and advanced concepts for propulsion
applications, such as hydrocarbon fuels for liquid boost, liquid and solid oxidizers for boost and upper stages, monopropellants
for spacecraft and upper stages, cryogenic propellants for upper stages and laser light craft for microsatellite and other
applications.

Report No.(s): AD-A410664; AFRL-PR-ED-VG-2002-068; No Copyright; Avail: CASI; A02, Hardcopy
The program objective is to identify and develop advanced chemical propellants for rocket propulsion applications.
Computational chemistry plays a critical role in HEDM research. It guides the choice of target compounds and possible
synthetic routes, and provides verification of successful synthesis. CC is addressing an ever wider range of Air Force
applications. New methods are under development (e.g. modeling chemistry in solution or on surfaces). Parallel computing
technology has greatly expanded the scope of problems which can be modeled.

New Polynitrogen Molecules: Energetic Air as a Next-Generation Propellant?
Boatz, Jerry A.; Christe, Karl O.; April 29, 2002; 5 pp.; In English

The identification, development, and formulation of new energetic materials for advanced rocket propulsion applications
is an area of long-standing interest to the Air Force. The performance limits of currently used propellants have been reached,
so new energetic compounds are required to significantly improve the ability of the warfighter to access and control space.
Polynitrogen species such as the recently discovered N5+ cation are of interest as potential energetic ingredients in new
propellant formulations. Conventional techniques for characterizing polynitrogens have relied heavily on costly and
