Abstract : A supersonic HF laser nozzle, BCL-16, has been used to produce high densities of NF(a(sup 1) delta) from the N2F4 + H2 reaction scheme. Through parametric studies, the flow rates to obtain optimum NF(a (sup 1) delta) production were determined. The NF(a (sup 1) delta ) molecule has been considered for use as an energy storage and energy transfer molecule. The NF(a (sup 1) delta) molecule is also a precursor of the highly energetic N2(A) molecule. The N2(A) species has also been considered as an excellent energy transfer molecule. The NF(a (sup 1) delta ) and NF(b (sup 1) sigma) density spatial profiles were determined as a function of flow rate. Yields were determined and mixing examined.
