Physical Chemistry of Energetic Nitrogen Compounds
Abstract
Photolysis of nitrogen trichloride at 193 nm efficiently produces the excited singlet delta state of NC1, a species useful as an energy carrier in atomic iodine lasers. Photolysis of mixtures of nitrogen trichloride with molecular iodides at 193 nm produces strong emission at 1315 nm from excited iodine atoms. Rate constants for the collisional quenching of excited singlet delta NC1 and excited iodine atoms by nitrogen trichloride were determined at room temperature. In a second part of the research, the deposition of BN films from the dissociation of boron triazide was investigated using plasma-assisted deposition methods. These experiments produced stable, dense, and adherent BN films with good chemical characteristics. The films were found to be amorphous, though, a result thought to be associated with self-assembly of boron triazide dissociation fragments into PN nanoparticles in the gas phase. This hypothesis was supported by IR analysis of the constituents of a boron triazide/argon plasma trapped in a low temperature matrix.
