Photographic Spectroscopic Measurement of Ultraviolet Solid Rocket Motor Plumes.
Abstract
Photographic spectra having a nominal bandpass of 0.4nm were obtained from the radiation from several solid rocket motor exhausts in the spectral region 250nm to 430 nm. The spectra consisted primarily of a continuum with some molecular band structure which was found to originate from the molecules OH, PbO, NO & CHO. These molecular bands were more pronounced in the region 290 nm to 320 nm, but the radiating systems involved extend to shorter wavelengths. The source of the continuum radiation was not determined explicitly, but is not inconsistent with a CO + O recombinations mechanism. (Author)
