Laser Spectroscopy of Oxygen Rings, Nitrogen Rings, and Other Novel High Energy Density Forms of Matter.
Abstract
New methods are explored for producing and characterizing proposed new HEDM molecules - covalent nitrogen and oxygen rings. A laser ablation 'supersonic catalytic plasma reactor' was developed, wherein a metal target is vaporized by a pulsed UV laser and reactant gases are added to the buffer gas. A pulsed corona discharge nozzle was developed for the same purpose. Cavity Ringdown and VUV laser ionization mass spectroscopy are Laser Absorption Spectroscopy developed for characterizing the products of the above sources. Initial tests of these sources for producing coinage metal silicides have been carried out. Cavity Ringdown Laser Absorption Spectroscopy has been extended into the infrared region of the spectrum using two different technologies. Studies of water clusters in pulsed supersonic beams and of molecules in flames have been carried out.
