Abstract:

This project is part of the search for a novel propellant based on molecules with excess internal energy for use in the combustion process. Spectroscopic properties of neutral molecules of triatomic hydrogen, tetraoxygen, superexcited oxygen, and hydronium were investigated using laser ionization, laser photodissociation, and charge neutralization techniques. The neutrals were prepared in a fast beam by electron transfer from stationary gas targets to mass selected ions. Excited state lifetimes and electronic, vibrational, and rotational-structures were examined as well as the dissociation products and the effect that external electric fields have on the stability of the molecules.
