N2(A3Epsilon u+) by Reaction of N2F4 + H2 in a Supersonic Flow.
Abstract
The Tetrafluorohydrazine + diatomichydrogen deuterium reaction has been used to produce NF a1Delta and NF b1Sigma in supersonic flow. The extension of that reaction sequence in excess hydrogen is that diatomic nitrogen (B) is produced which relaxes to the N2(A) electronic state with an energy content of 6.2 eV. The energy storage potential of N2(A) and subsequent transfer of energy to other molecules, such as, NO, SO and IF, makes this production method of extreme interest for laser applications. The device diagnostics, parametric studies and final yield of N2(A) are described. The yield of N2(A) is lower than expected from subsonic studies, but the experiments indicate areas of study required to understand the system in greater detail.
